Add reusable UI components for Phase 7 UI Polish

- Introduced `EmojiQuickGrid`, `FontPresetPicker`, and `PresetSizeToggle` classes for emoji selection, font presets, and size toggles respectively. - Implemented configuration methods for each component to handle dynamic content and theming. - Created tests for the new components to ensure functionality and integration with the existing UI. - Added a comprehensive architecture specification for Phase 7 UI Polish detailing scope, implementation, and validation strategies. - Updated existing theme handling to support new UI elements and ensure consistent styling across the application.

 #### 21.3 `res://sandbox_theme.json` (styling defaults)
-A single committed, hand-editable JSON config drives sandbox font/size/color/grid defaults. It loads in `_ready()` before `_build_ui()`; a missing or malformed file logs one `push_warning` and uses all built-in constants (never crashes); unknown extra keys are ignored; a referenced font that does not exist falls back to `ThemeDB.fallback_font` with a warning. The **live** grid size/snap/grid-visibility remain persisted in `user://sandbox_settings.json` (runtime source of truth); the theme supplies the **initial default** grid size on first run. Schema:
+The Sandbox theme is schema `2.0` and now covers the code-built chrome,
 palette, selectors, dialogs, overlays, reusable widget data, fonts, colors,
 and grid defaults. See the complete current key reference, examples, legacy
 compatibility notes, and troubleshooting guide in
 [docs/SANDBOX_THEME.md](docs/SANDBOX_THEME.md).

 | Key | Default | Consumed by |
 |---|---|---|
 | `fonts.ui_font` / `fonts.emoji_font` | `""` (fallback font) | `res://` font paths; empty/missing → `ThemeDB.fallback_font`. `emoji_font` is also pushed to `StageDirectorVisuals.emoji_font` and the director popups. |
 | `fonts.ui_font_bold` / `fonts.ui_font_italic` | `""` (fallback to `ui_font`) | **Phase 3c** style-variant font paths for bold/italic; empty → `ui_font`. Bold/italic are realised via a dedicated `FontVariation` (e.g. `variation_embolden`, OpenType slant) when no separate file is configured. |
 | `fonts.action_popup_font_size` / `action_popup_emoji_size` | 24 / 22 | Font size override on the director action/trigger/rule popups. **Phase 3c:** `action_popup_emoji_size` is now **consumed** — applied as the popup menu's emoji-glyph font size when a popup font is configured (`_apply_popup_theme()`). |
 | `fonts.action_popup` (optional object) | `{ "size": 24, "bold": false, "italic": false }` | **Phase 3c** per-widget object form for the popups; when present, overrides the flat `action_popup_font_size` / bold keys for that widget. |
 | `fonts.assignment_badge_font_size` / `assignment_badge_radius` | 20 / 9 | Replaces `StageDirectorVisuals` `ICON_SIZE_PX` / `RULE_BADGE_RADIUS_PX` (and order-number size) via `set_style(cfg)`. |
 | `fonts.rule_label_font_size` | 16 | Replaces `StageDirectorVisuals.RULE_LABEL_FONT_SIZE_PX`. **Phase 3c** `fonts.rule_label_bold` (default `false`) adds the bold flag; `fonts.badge_bold` (default `true`) bolds the action/trigger badges. |
 | `fonts.status_pill_font_size` / `tooltip_font_size` | 16 / 18 | The mode badge pill and the cursor-attached action tooltip. |
 | `fonts.queue_panel_font_size` / `rule_panel_font_size` | 18 / 18 | **Phase 3c** font sizes for the Queue / Rule panel bodies; fall back to `action_popup_font_size`. |
 | `fonts.action_editor_font_size` / `rule_editor_font_size` | 18 / 18 | **Phase 3c** font sizes for the Action / Rule editors; fall back to `action_popup_font_size`. |
 | `fonts.panel_row_font_size` / `panel_title_font_size` | 16 / 18 | **Phase 3c** per-row summary/number label and panel title label sizes; `fonts.panel_title_bold` (default `true`) bolds panel titles. |
 | `grid.snap_size` | 15.0 | Initial default grid size for the Size spinbox (first run). |
 | `mode_colors.edit_accent` / `direct_accent` / `play_accent` | `#22c6ff` / `#ffb300` / `#33dd77` | Mode badge pill bg, the Direct viewfinder frame, the active mode-segment text, and tooltip border. |
 | `mode_colors.guide_line` | `#22c6ff` | The terrain drag-painting dashed guide line (`StagePlacementOverlay.guide_line_color`). |
 `StageDirectorVisuals.set_style(cfg)` applies the `fonts` keys onto instance vars (`badge_icon_size`, `badge_number_size`, `badge_radius`, `rule_label_font_size`) whose defaults equal the old constants, so behavior is unchanged when no theme is present.
 **Phase 3c theming (font styles/sizes):** the Phase 3c widgets now accept an `apply_font(ui_font, emoji_font, sizes)` call — `QueuePanel`, `RulePanel`, `ActionEditor`, and `RuleEditor` (see §23) each expose it (mirroring `AssetSelector.apply_font`), and `SandboxStage._build_ui()` invokes it **after** `add_child(...)`. Per-widget sizes come from the `*_panel_font_size` / `*_editor_font_size` / `panel_row_font_size` / `panel_title_font_size` keys; bold/italic style flags (`panel_title_bold`, `rule_label_bold`, `badge_bold`) and a widget's optional `{size, bold, italic}` object form are applied via the `ui_font_bold` / `ui_font_italic` `FontVariation`-derived font. The `PopupMenu`s (rig/waypoint context) keep `_apply_popup_theme()`, extended to honour `action_popup_emoji_size` and the `action_popup` object form. Authoritative schema: `docs/phase_3c_editor_spec.md` §14.
 **Director-context rule-connector refresh (bugfix):** `SandboxStage._on_transform_committed()` now calls `StageDirectorVisuals.mark_dirty()` after a move/rotate, so **translating a `TriggerArea` (or any rule-anchoring object) moves its dashed connector and ⚡/→ badges** to the new position on drag end. (Rule anchors were already computed live each `_draw()`; the missing `mark_dirty()` was leaving them stale because a `_draw()` never ran.) Deleting a referenced area already triggers `_cleanup_rules_for_nodes → set_rules → mark_dirty`.

 # Sandbox theme reference
 `res://sandbox_theme.json` is the hand-editable presentation configuration for
 the Sandbox Stage (`res://scenes/sandbox_stage.tscn`). It is loaded by
 `SandboxStage` during `_ready()`, before the code-built UI is created. The
 loader is `res://scripts/sandbox_theme.gd` (`class_name SandboxTheme`).
 The committed file uses schema `"2.0"`. The theme controls presentation
 defaults only; it does not save a scene, placement, or action data.
 ## Load, merge, and validation rules
 The load path is:
 ```text
 res://sandbox_theme.json
        │
        ▼
 SandboxTheme.DEFAULT_CONFIG
        │ deep-merge file values
        ▼
 SandboxStage._build_ui() and visual overlays
 ```
 - Missing, unreadable, malformed, or non-object JSON uses the built-in default
  configuration and emits one warning. The stage continues to run.
 - Missing nested keys inherit the built-in value. Unknown keys are retained in
  the raw dictionary but have no effect until a consumer is added.
 - `stylebox(component)` resolves styles in this order:
  `global` → `<section>.style_defaults` → the component object. For example,
  `palette` is resolved from `global`, then `palette.style_defaults`, then
  `palette`.
 - Colors must be strings in `#RRGGBB` or `#RRGGBBAA` form. Invalid colors use
  the requested fallback and emit a warning.
 - Numeric accessors accept finite integers/floats and clamp them to the range
  requested by the consumer. Invalid or non-finite numbers use that consumer's
  fallback. Size arrays are accepted when they contain two numeric values;
  individual controls apply their own minimum sizes.
 - Font paths are `res://` resource paths. A missing resource, or a resource
  that is not a `Font`, uses `ThemeDB.fallback_font` and emits a warning.
 - The theme is loaded once per Sandbox Stage instance. Restart the scene (F6)
  to see edits; there is no live file watcher or reload button.
 The live grid size, snap toggle, and grid visibility are stored in
 `user://sandbox_settings.json`. `grid.snap_size` supplies the initial grid-size
 default; it does not overwrite a value already saved in user settings.
 ## Schema overview
 Every current top-level block is listed below. The values shown are the
 defaults in the committed `sandbox_theme.json` (not necessarily the fallback
 used by an older caller).
 ### Current consumer status
 The schema intentionally includes forward-looking values for the reusable
 widget and speech work. The current Sandbox runtime applies these groups:
 - `global` style values used by resolved styleboxes and the selector control
  theme (background/border/radius/padding); `global.text_color` and
  `global.muted_text_color` are available presentation values but are not
  applied to every existing label automatically.
 - `fonts.ui_font`, `emoji_font`, bold/italic variants, the nested `sizes`
  entries for action popups, tooltips, status pills, queue/rule/action editors,
  panel rows/titles, `file_menu`, `file_menu_popup`, and `mode_switcher`, plus
  the related `flags`.
 - `mode_colors.edit`, `direct`, `play`, and `guide`; `grid.snap_size` as the
  first-run grid default; dialog sizes/fonts; `chrome.mode_switcher` width;
  palette width/card size/drag threshold/style; selector cell and thumbnail
  sizes; and all `overlays` values.
 These declared values currently remain reserved or require a legacy adapter:
 - `chrome.top_bar.height`, `status_bar.height`, `mode_frame`, `mode_badge`,
  and `tooltip` describe the intended chrome contract, but the corresponding
  layout/style constants are still authored in `SandboxStage`.
 - `popups.action_menu.font_size` and `popups.asset_selector.backdrop_alpha`
  are reserved component overrides. The active action-menu size comes from
  `fonts.sizes.action_popup`; selector `cell_size` and `thumbnail_size` are
  active.
 - `palette.icon_size` and `palette.selected_border_width` are reserved for
  the palette card renderer; the current card has its own glyph/border values.
 - `fonts.sizes.assignment_badge`, `rule_label`, `asset_label`, and
  `asset_badge` are part of the resolved schema, but the current direct call
  into `StageDirectorVisuals` still reads the legacy flat badge/label names.
  Use the legacy names documented below when changing those director visuals.
 - `fonts.presets` and every `widgets` list are exposed through reusable
  controls, but the current Sandbox Speak action does not instantiate those
  controls yet. They are future speech-customization data.
 ### `version`
 | Key | Format | Current value | Notes |
 |---|---|---:|---|
 | `version` | string | `"2.0"` | Use `"2.0"` when using the nested schema below. |
 ### `global`
 Global style values are inherited by `SandboxTheme.stylebox()` and the default
 control theme.
 | Key | Format | Default | Purpose |
 |---|---|---:|---|
 | `font_preset` | string | `"ui"` | Named base-font selection for future/general UI use. |
 | `font_size` | integer | `18` | Default `Control` font size. |
 | `text_color`, `muted_text_color` | color string | `#F5F7FA`, `#AAB2C0` | Primary and secondary text colors. |
 | `bg_color`, `surface_color` | color string | `#171B24F2`, `#252B38FA` | Global and raised-surface backgrounds. |
 | `border_color` | color string | `#FFFFFF33` | Default border color. |
 | `border_width` | integer | `1` | Default border width. |
 | `corner_radius` | integer | `10` | Default corner radius. |
 | `padding`, `spacing` | integer | `8`, `8` | Default style padding and layout spacing. |
 ### `fonts`
 Font paths may be empty (`""`) to use the engine fallback. `presets` is an
 object of arbitrary preset IDs; each entry has a display `label` and a `path`.
 The committed file provides `ui`, `comic`, `pixel`, and `scary` entries.
 | Key | Format | Default | Consumer |
 |---|---|---:|---|
 | `ui_font`, `emoji_font` | `res://` path or empty | `""` | Base UI and emoji-capable stage/director controls. |
 | `ui_font_bold`, `ui_font_italic` | `res://` path or empty | `""` | Optional style variants; bold can be generated from the base font when no dedicated path is supplied. |
 | `presets` | object `{id:{label,path}}` | see JSON | `font_presets()` and future font selectors. |
 | `sizes.action_popup` | integer | `24` | Director/action popup text. |
 | `sizes.action_popup_emoji` | integer | `22` | Effective popup size when a popup font is active (Godot popup menus have one font size). |
 | `sizes.assignment_badge` | integer | `20` | Reserved resolved-theme value; current director visuals use legacy `fonts.assignment_badge_font_size`. |
 | `sizes.rule_label` | integer | `18` | Reserved resolved-theme value; current director visuals use legacy `fonts.rule_label_font_size`. |
 | `sizes.status_pill` | integer | `18` | Mode badge/pill. |
 | `sizes.tooltip` | integer | `18` | Cursor-attached targeting tooltip. |
 | `sizes.file_menu` | integer | `22` | `File` button in the top bar. |

 | `flags.action_popup_bold`, `flags.action_popup_italic` | boolean | `false`, `false` | Popup style flags. |
 ### `mode_colors`
 Each value is a color string. These accents are used by the mode badge/frame,
 active mode controls, targeting feedback, and related stage chrome.
 | Key | Default | Purpose |
 |---|---|---|
 | `edit` | `#22C6FF` | Edit-mode accent. |
 | `direct` | `#FFB300` | Direct-mode accent. |
 | `play` | `#33DD77` | Play-mode accent. |
 | `guide` | `#22C6FF` | Terrain painting guide line. |
 ### `grid`
 | Key | Format | Default | Purpose |
 |---|---|---:|---|
 | `snap_size` | finite number | `15.0` | Initial grid size, clamped to the stage's supported range. |
 ### `chrome`
 `style_defaults` is the optional common style object for chrome components. Its
 style keys follow the `global` style formats (`bg_color`, `border_color`,
 `border_width`, `corner_radius`, `padding`).
 | Key | Format | Default | Purpose |
 |---|---|---:|---|
 | `style_defaults` | style object | `{ "bg_color":"#171B24F2", "corner_radius":10 }` | Shared chrome style base. |
 | `top_bar.height` | number | `64` | Top navigation bar height. |
 | `status_bar.height` | number | `38` | Bottom status bar height. |

 | `dialogs.confirm_size` | `[width,height]` | `[620,300]` | Rename, unsaved, missing-assets, and other confirmation/error windows. |
 | `dialogs.font_size` | integer | `22` | Dialog controls/buttons. |
 | `dialogs.message_font_size` | integer | `26` | Centered AcceptDialog message text. |
 ### `popups`
 `style_defaults` accepts the normal style keys and is inherited by popup
 components.
 | Key | Format | Default | Purpose |
 |---|---|---:|---|
 | `style_defaults` | style object | bg `#202633FA`, border `#FFFFFF33`, radius `12`, padding `12` | Common popup surface. |
 | `action_menu.font_size` | integer | `24` | Reserved action-menu component override; use `fonts.sizes.action_popup` for the active menu. |
 | `dialog` | object | `{}` | Reserved per-dialog popup overrides. |
 | `asset_selector.backdrop_alpha` | finite number | `0.55` | Reserved selector backdrop opacity. |
 | `asset_selector.cell_size` | `[width,height]` | `[190,220]` | Prop/stickman selector cell size. |
 | `asset_selector.thumbnail_size` | `[width,height]` | `[156,156]` | Prop/stickman selector thumbnail size. |
 ### `palette`
 `style_defaults` uses normal style keys and styles the stage placement palette.
 | Key | Format | Default | Purpose |
 |---|---|---:|---|
 | `style_defaults` | style object | bg `#252B38FA`, radius `10`, padding `6` | Palette surface/card base. |
 | `dock_width` | number | `116` | Palette width in Edit mode and stage-frame inset. |
 | `card_size` | `[width,height]` | `[96,94]` | Placement-card minimum size; the card keeps room for its label. |
 | `icon_size` | number | `30` | Reserved palette icon/glyph size. |
 | `drag_threshold` | number | `8` | Pointer distance before a card becomes a drag. |
 | `selected_border_width` | integer | `3` | Reserved selected palette card border. |
 ### `overlays`
 `style_defaults` controls dashed overlay geometry in world pixels; colors are
 RGBA strings.
 | Key | Format | Default | Purpose |
 |---|---|---:|---|
 | `style_defaults.line_width` | number | `2` | Dashed trajectory/guide width. |
 | `style_defaults.dash_length` | number | `8` | Dash length. |
 | `style_defaults.dash_gap` | number | `5` | Gap length. |
 | `terrain_guide.color` | color | `#22C6FF` | Terrain paint guide. |
 | `valid.color` | color | `#4DE66680` | Valid director target/placement feedback. |
 | `same_type.color` | color | `#FFFFFF26` | Same-type placement feedback. |
 | `invalid.color` | color | `#FF4D4D80` | Invalid target/placement feedback. |
 ### `widgets`
 These lists feed reusable controls (`EmojiQuickGrid`, `FontPresetPicker`, and
 `PresetSizeToggle`). They are data sources, not speech-action persistence.
 | Key | Format | Default | Purpose |
 |---|---|---|---|
 | `swatches` | array of color strings | white, black, cyan, amber, green, red | Color selector entries. |
 | `size_presets` | array of `{id,label,value}` objects | Small/Medium/HUGE (`20/28/40`) | Size selector entries; `value` is an integer-like size. |
 | `emoji` | array of strings | eight emoji entries | Emoji quick-grid entries. |
 ## Practical edits
 Make the top navigation easier to read:
 ```json
 {
  "fonts": {
    "sizes": {
      "file_menu": 26,
      "file_menu_popup": 30,
      "mode_switcher": 28
    }
  }
 }
 ```
 Change the mode frame and make the stage colors more distinct:
 ```json
 {
  "mode_colors": {
    "edit": "#4DD9FF",
    "direct": "#FF8A3D",
    "play": "#65E68A",
    "guide": "#4DD9FF"
  },
  "chrome": { "mode_frame": { "border_width": 4 } }
 }
 ```
 Give selectors larger cards and thumbnails:
 ```json
 {
  "popups": {
    "asset_selector": {
      "cell_size": [220, 260],
      "thumbnail_size": [190, 190]
    }
  }
 }
 ```
 Make kid-facing editors and confirmations larger:
 ```json
 {
  "chrome": {
    "dialogs": {
      "queue_size": [760, 600],
      "rule_size": [800, 640],
      "font_size": 26,
      "message_font_size": 30
    }
  },
  "fonts": {
    "sizes": {
      "queue_panel": 24,
      "rule_panel": 24,
      "action_editor": 24,
      "rule_editor": 24,
      "panel_row": 22,
      "panel_title": 28
    }
  }
 }
 ```
 ## Legacy v1 files
 Older Phase 4b/3c theme files used flat keys such as
 `fonts.action_popup_font_size`, `fonts.queue_panel_font_size`,
 `fonts.panel_title_font_size`, and mode keys such as
 `mode_colors.edit_accent` and `mode_colors.guide_line`. They remain accepted.
 The loader aliases the legacy mode names and selected flat font-size names into
 the nested structure, while `SandboxStage` retains the old precedence for a
 file that does not declare version `"2.0"`.
 The complete legacy names still read by the current runtime are:
 ```text
 fonts.action_popup_font_size       fonts.action_popup_emoji_size
 fonts.assignment_badge_font_size  fonts.assignment_badge_radius
 fonts.rule_label_font_size        fonts.status_pill_font_size
 fonts.tooltip_font_size           fonts.queue_panel_font_size
 fonts.rule_panel_font_size        fonts.action_editor_font_size
 fonts.rule_editor_font_size       fonts.panel_row_font_size
 fonts.panel_title_font_size       fonts.panel_title_bold
 fonts.rule_label_bold             fonts.badge_bold
 fonts.action_popup = { size, bold, italic }
 mode_colors.edit_accent           mode_colors.direct_accent
 mode_colors.play_accent            mode_colors.guide_line
 ```
 For a migration, copy the values into the nested keys in this document and set
 `"version": "2.0"`. Keep only one spelling of each setting so the result is
 easy to maintain.
 ## Fonts, emoji, and troubleshooting
 - Use project-relative paths such as `res://fonts/kids_font.ttf`; do not use a
  machine-specific absolute path.
 - If text falls back to the Godot default, check the path, import status, and
  that the resource is actually a `Font`/font file. Restart the Sandbox after
  correcting it.
 - Emoji availability depends on the selected font and platform glyph support.
  A missing `emoji_font` is non-fatal; the normal UI fallback remains usable.
 - If a color or number is ignored, check JSON commas/quotes, use a supported
  color form, and keep numbers finite. The warning identifies the affected key.
 - If a selector or dialog looks cramped, increase its size array and its
  related font size together; restart F6 to reload the file.
 ## Speech customization status
 `fonts.presets` (`ui`, `comic`, `pixel`, `scary`), `widgets.size_presets`,
 `widgets.swatches`, and `widgets.emoji` are the reusable data contract for a
 future speech-customization UI. They are intentionally available now so a
 future Speak dialog can consume the same theme.
 The current Sandbox speech action still stores and renders text through the
 existing `StickmanSpeechBubble`; these theme lists do not yet change saved
 speech actions, bubble shape, bubble colors, or bubble font at runtime. Do not
 assume that changing a preset changes an existing speech action. Treat
 speech-specific fields under `popups.dialog` or future bubble sections as
 reserved until that feature is implemented.

 # Phase 7 UI Polish — Architecture Specification
 Status: **proposed; awaiting user approval**  
 Source plan: `plans/PHASE_7_UI_POLISH.md`  
 Target: Godot 4.7.1 Sandbox Stage only. The configured Stickman Editor main scene is not changed.
 ## 1. Scope and current-state audit
 Phase 7 is an incremental polish pass, not a rewrite of `SandboxStage`. The stage scene remains deliberately small and the runtime UI remains owned by `SandboxStage._build_ui()`. Existing tests also access several stage fields directly, so moving the full UI into a new scene would add migration risk without improving the requested behavior.
 ### Already implemented; preserve and restyle
 | Plan item | Existing implementation |
 |---|---|
 | Three mode controls | `_mode_buttons` in `scripts/sandbox_stage.gd` |
 | Mode badge, status text, live world coordinates | `_mode_badge`, `_status_label`, `_status_cursor_coords` |
 | Mode cursor and target reticle | `_apply_cursor()`, `_build_action_cursor()` |
 | Cursor tooltip and direct-action trajectory | `_tooltip`, `StagePlacementOverlay.set_action_trajectory()` |
 | Terrain AABB stride, Bresenham painting, Shift lock | `_terrain_stride()`, `_bresenham_cells()`, `_update_terrain_drag()` |
 | Three-state terrain ghosts | `_classify_cell()`, `_refresh_terrain_ghosts()` |
 | Asset selector with thumbnail cards and dimmer | `asset_selector.tscn`, `asset_selector.gd`, `_selector_dim` |
 | Sequential off-screen thumbnail rendering and disk cache | stage `_thumbnail_queue`; `scripts/thumbnails/*` |
 | Popup and editor font overrides | `_apply_popup_theme()` and widget `apply_font()` methods |
 These behaviors are integration points, not new Phase 7 systems. Their public behavior and existing headless tests must continue to pass.
 ### In Phase 7
 1. Replace the stage-local JSON parsing and scattered style constants with a validated, cached `SandboxTheme` service and schema version 2.
 2. Give the existing mode switcher, viewport frame, badge, status bar, tooltips, popups, dialogs, selector, and overlays a coherent theme-driven appearance.
 3. Replace the top-row spawn text buttons with a scrollable graphical card palette. Clicking keeps the existing persistent placement behavior; dragging a card performs one placement.
 4. Harden the existing thumbnail cache with a memory tier and stale-request protection. Rendering remains serialized on the main thread.
 5. Add reusable color, size, font-preset, and emoji controls, with stable typed APIs, ready for later parameter dialogs.
 ### Explicitly deferred
 - Speech bubble geometry/styles, custom speech rendering, and changes to persisted `speak` actions. Section 10 defines the future contract, but Phase 7 does not emit or consume it.
 - Embedding the four new reusable widgets into the Speak dialog. That is the first consumer in the future speech-customization phase.
 - True background-thread thumbnail rendering. Godot scene/viewport rendering remains main-thread work; Phase 7 limits generation to one job at a time and avoids duplicate/stale work.
 - Dragging cards out of the modal `AssetSelector`. Direct drag uses the currently selected Prop or Stickman card in the persistent palette; the modal remains click-to-select.
 - New bitmap icon art. Phase 7 uses registry-provided emoji glyphs plus existing generated thumbnails. Art assets can replace them later without changing card APIs.
 - A full `.tscn` conversion of the code-built Sandbox UI.
 ## 2. Files
 ### Add
 - `scripts/sandbox_theme.gd` — `class_name SandboxTheme`, schema validation, legacy aliases, typed accessors, font/style/theme caches.
 - `scripts/ui/asset_card.gd` — `class_name AssetCard`, reusable palette/selector card and pointer-drag threshold handling.
 - `scripts/ui/color_swatch_selector.gd` — `class_name ColorSwatchSelector`.
 - `scripts/ui/preset_size_toggle.gd` — `class_name PresetSizeToggle`.
 - `scripts/ui/font_preset_picker.gd` — `class_name FontPresetPicker`.
 - `scripts/ui/emoji_quick_grid.gd` — `class_name EmojiQuickGrid`.
 - `tests/test_phase7_theme.gd` — schema, fallback, alias, and resource/cache behavior.
 - `tests/test_phase7_widgets.gd` — widget data contracts and signals.
 - `tests/test_phase7_palette.gd` — card activation/drag state, mode visibility, and placement behavior.
 The reusable controls are script-built `Control` subclasses, not new scenes. They have no project-specific node paths and can be instantiated in any popup.
 ### Change
 - `sandbox_theme.json` — migrate the committed theme to schema `2.0`.
 - `scripts/sandbox_stage.gd` — own `SandboxTheme`; build/stylize the chrome and palette; route card drag input; use theme accessors; apply theme to popups/dialogs; add thumbnail request generation tokens.
 - `scripts/stage_spawner.gd` — expose registry-backed palette descriptors without exposing `_registry`.
 - `scripts/asset_selector.gd` — build cells with `AssetCard`; accept a `SandboxTheme`; keep current signals and pagination.
 - `scenes/asset_selector.tscn` — name layout containers used for theme spacing/margins and remove hard-coded visual values now owned by the theme. Node unique names and popup behavior remain compatible.
 - `scripts/thumbnails/thumbnail_cache.gd` — add an in-memory texture tier and versioned cache API while preserving current path helpers.
 - `scripts/stage_placement_overlay.gd` — accept resolved overlay colors/metrics through one style method; drawing/input behavior is unchanged.
 - `scripts/stage_director_visuals.gd` — consume a resolved style dictionary rather than reading raw schema internals; preserve `set_style(Dictionary)` as a compatibility wrapper.
 - `scripts/action_editor.gd`, `scripts/rule_editor.gd`, `scripts/queue_panel.gd`, `scripts/rule_panel.gd` — add `apply_theme(theme: SandboxTheme)` wrappers and retain current `apply_font(...)` methods for existing tests/callers.
 - Existing Phase 3b/3c/4b tests only where assertions must reflect the always-visible mode frame or v2 key names; behavioral coverage is not removed.
 ### Not changed in Phase 7
 - `scenes/sandbox_stage.tscn`
 - `scripts/action_registry.gd`
 - `scripts/stage_scene_io.gd`
 - `scripts/stickman_rig.gd`
 - `scripts/stickman_speech_bubble.gd`
 ## 3. `sandbox_theme.json` schema 2.0
 The JSON remains hand-editable. Colors are HTML strings (`#RRGGBB` or `#RRGGBBAA`), resource paths are strings, dimensions are logical screen pixels, and preset IDs are stable lowercase strings.

 Array values such as `card_size` must contain exactly two finite numbers. Unsupported or malformed values fall back independently; one bad field does not discard the rest of the file.
 ### Resolution order
 For a component such as `popups.action_menu`, the service deep-merges, from lowest to highest priority:
 1. Hard-coded `SandboxTheme.DEFAULT_CONFIG` value.
 2. Loaded `global` value.
 3. Loaded subsystem `popups.style_defaults` value.
 4. Loaded component `popups.action_menu` value.
 Font resolution is: component `font_preset`/explicit path → subsystem default → `global.font_preset` → `fonts.ui_font` → `ThemeDB.fallback_font`. An unavailable named preset falls back to `ui`. Emoji font resolution is `fonts.emoji_font` → resolved UI font → `ThemeDB.fallback_font`.
 ### Validation, warnings, and caching
 - Missing, unreadable, malformed, or non-dictionary JSON produces one non-blocking `push_warning` and a complete default config.
 - A wrong type, non-finite number, bad color, or missing/non-Font resource warns once per key and falls back only that key.
 - Unknown keys are retained in `raw_config()` for forward compatibility but are ignored by typed accessors.
 - Fonts are loaded once per normalized non-empty resource path in `_font_cache`.
 - Resolved `StyleBoxFlat` templates are cached by the canonical resolved style dictionary. `stylebox()` returns a duplicate so mode-specific color mutation cannot leak into another control.
 - The generated Godot `Theme` is cached. Call `invalidate_caches()` only after an explicit reload; Phase 7 does not add live file watching.
 - No theme resource failure may prevent Sandbox startup.
 ## 4. `SandboxTheme` public contract
 ```gdscript
 class_name SandboxTheme
 extends RefCounted
 const SCHEMA_VERSION: String = "2.0"
 const DEFAULT_PATH: String = "res://sandbox_theme.json"
 func load_from(path: String = DEFAULT_PATH) -> bool
 func raw_config() -> Dictionary
 func value(path: String, fallback: Variant = null) -> Variant
 func color(path: String, fallback: Color) -> Color
 func number(path: String, fallback: float, minimum: float = -INF, maximum: float = INF) -> float
 func integer(path: String, fallback: int, minimum: int = -2147483648, maximum: int = 2147483647) -> int
 func font(component_path: String = "", preset_id: String = "ui") -> Font
 func emoji_font() -> Font
 func style(component_path: String) -> Dictionary
 func stylebox(component_path: String) -> StyleBoxFlat
 func control_theme() -> Theme
 func swatches() -> Array[Color]
 func size_presets() -> Array[Dictionary]
 func font_presets() -> Array[Dictionary]
 func emoji_items() -> Array[String]
 func invalidate_caches() -> void
 ```
 `raw_config()` returns a deep duplicate. The preset array entries returned by `size_presets()` are `{id: String, label: String, value: int}`; font preset entries are `{id: String, label: String, font: Font}`. Invalid entries are omitted, while a built-in medium size and UI font are always available.
 No reload signal is needed in Phase 7 because the theme loads once before UI construction. A later live-theme editor may add `theme_reloaded()` without changing the accessor API.
 ## 5. Palette descriptors and controls
 ### `StageSpawner` API
 Add:
 ```gdscript
 func get_palette_entries() -> Array[Dictionary]
 ```
 Each returned deep-duplicated entry has this shape:
 ```gdscript
 {
    "placement_id": String, # existing id accepted by set_placement_mode()
    "kind": String,         # "terrain" | "prop" | "stickman" | "area"
    "label": String,
    "icon": String,         # emoji fallback, not a resource path
    "category": String,     # visible badge/group label
    "opens_selector": bool
 }
 ```
 Registry defaults are Ground/🧱/Terrain, Ramp/📐/Terrain, Step/🪜/Terrain, Prop/📦/Props, Stickman/🧍/Cast, and Area/🎯/Events. `get_spawnable_ids()` and `get_label()` remain unchanged.
 ### `AssetCard`
 ```gdscript
 class_name AssetCard
 extends Button
 signal activated(payload: Dictionary)
 signal drag_started(payload: Dictionary)
 func configure(payload: Dictionary, icon_texture: Texture2D = null, theme: SandboxTheme = null) -> void
 func set_thumbnail(texture: Texture2D) -> void
 func set_selected(selected: bool) -> void
 func payload() -> Dictionary
 ```
 The payload is deep-copied on input and signal emission. The card owns icon/thumbnail, label, and optional category badge children. It emits `activated` on a release that stayed below `palette.drag_threshold`; after the threshold it emits `drag_started` once and suppresses activation. It does not mutate stage or spawner state directly.
 ### Reusable widget APIs
 ```gdscript
 # ColorSwatchSelector
 signal color_selected(color: Color)
 func configure(colors: Array[Color], selected: Color, theme: SandboxTheme = null) -> void
 func set_selected(color: Color, emit_signal: bool = false) -> void
 func get_selected() -> Color
 # PresetSizeToggle
 signal preset_selected(id: String, value: int)
 func configure(presets: Array[Dictionary], selected_id: String, theme: SandboxTheme = null) -> void
 func set_selected(id: String, emit_signal: bool = false) -> void
 func get_selected_id() -> String
 func get_selected_value() -> int
 # FontPresetPicker
 signal preset_selected(id: String)
 func configure(presets: Array[Dictionary], selected_id: String, theme: SandboxTheme = null) -> void
 func set_selected(id: String, emit_signal: bool = false) -> void
 func get_selected_id() -> String
 # EmojiQuickGrid
 signal emoji_selected(text: String)
 func configure(items: Array[String], columns: int = 8, theme: SandboxTheme = null) -> void
 ```
 All configure methods replace prior children, tolerate empty inputs, use a `ButtonGroup` for exclusive preset selection, expose keyboard focus, and meet a minimum 44×44 logical-pixel pointer target.
 ## 6. Node ownership and layout
 `SandboxStage` continues to create one `CanvasLayer` named `UI`. Its runtime ownership becomes:
 ```text
 SandboxStage (Node2D; state and orchestration)
 ├── GridLayer / World / GhostHolder / PlacementOverlay / DirectorVisuals (world space)
 └── UI (CanvasLayer)
    ├── ModeFrame (Panel; full rect; mouse ignore)
    ├── TopBar (PanelContainer)
    │   └── FileMenu + ModeSwitcher + edit/direct utility controls
    ├── PaletteDock (PanelContainer; left, below TopBar and above StatusBar)
    │   └── ScrollContainer/PaletteCards (VBoxContainer of AssetCard)
    ├── ModeBadge (PanelContainer; mouse ignore)
    ├── ActionTooltip (Label; mouse ignore)
    ├── BottomStatusBar (PanelContainer)
    ├── SelectorDim (ColorRect; visible only with selector)
    └── Popups/dialogs/selectors/editors
 ```
 `PaletteDock` is visible only in EDIT. Existing grid/snap/size controls remain in `TopBar`; spawn buttons leave the top row. `_palette_buttons` is retained and maps placement IDs to `AssetCard` (a `Button` subclass), preserving callers that inspect `button_pressed`/`visible`.
 The mode segments share a `ButtonGroup`, have adjacent rounded styles, and retain `_on_mode_segment_toggled`. `_mode_frame` is visible in all three modes and uses the active accent; it remains behind all chrome and ignores mouse input. The badge remains below the top bar and displays the existing text.
 The stage assigns `theme.control_theme()` to the UI root and explicitly to Window-derived popups/dialogs that do not reliably inherit across a native/embedded window boundary. Component styleboxes are then applied only where a named component override is needed.
 ## 7. Input and signal flow
 ### Click placement
 1. `AssetCard.activated(payload)` reaches `SandboxStage._on_palette_card_activated(payload)`.
 2. Terrain/Area calls existing `set_placement_mode(placement_id)`.
 3. Prop/Stickman opens the existing selector; selecting an entry updates the spawner and arms the existing `prop`/`stickman` placement ID.
 4. LMB remains repeated placement and RMB/Escape cancels, matching existing behavior.
 ### Direct card drag
 Godot Control drag-and-drop is not used because the drop surface is a `Node2D` world and a full-screen `Control` would compete with existing `_unhandled_input` selection/gizmo routing.
 1. `AssetCard.drag_started(payload)` calls `_begin_palette_drag(payload)`.
 2. The stage stores `_palette_drag_payload`, snapshots the prior placement ID, resolves current Prop/Stickman selection, and creates the normal collision-disabled placement ghost.
 3. While a palette drag is active, `SandboxStage._input` handles mouse motion and LMB release before pan/zoom routing. Tooltip/modal/rule input is not entered.
 4. A release is valid only inside the stage viewport and outside visible interactive chrome (`gui_get_hovered_control() == null` or a mouse-ignore overlay). Valid release places exactly one object at `_viewport_to_world(event.position)`, using existing snap/spawn/finalize/signals/dirty-state code.
 5. Release over UI, RMB, Escape, mode change, selector open, or focus loss cancels and frees the drag ghost.
 6. A card drag is one-shot and restores the previous persistent placement selection. It never starts terrain line-painting; terrain drag-painting still starts from a stage press after click-arming the tool.
 Add private state and helpers in `sandbox_stage.gd`:
 ```gdscript
 var _palette_drag_payload: Dictionary = {}
 var _palette_drag_previous_id: String = ""
 func _on_palette_card_activated(payload: Dictionary) -> void
 func _begin_palette_drag(payload: Dictionary) -> void
 func _update_palette_drag(viewport_pos: Vector2) -> void
 func _finish_palette_drag(viewport_pos: Vector2) -> void
 func _cancel_palette_drag() -> void
 func _is_stage_drop_position(viewport_pos: Vector2) -> bool
 ```
 Priority while active is palette drag → modal suppression → pan/zoom → existing world tools. Existing rule/capture/terrain/gizmo priorities remain unchanged when no palette drag is active.
 ## 8. Thumbnail pipeline
 The existing renderer nodes and queue remain stage-owned. Do not introduce threads.
 Extend `ThumbnailCache` with:
 ```gdscript
 func get_texture(cache_path: String) -> Texture2D
 func store_texture(cache_path: String, texture: Texture2D) -> Error
 func forget_memory(cache_path: String) -> void
 func clear_memory() -> void
 ```
 `get_texture()` checks an in-memory dictionary, then PNG, and memoizes success. `store_texture()` memoizes and persists. Existing `load_png()`/`save_png()` remain as compatibility wrappers.
 The stage increments `_thumbnail_generation: int` whenever selector entries change or the selector closes. Each queued job carries `{generation, kind, entry, cache_path}`. After each `await`, results update the selector only when the generation still matches, the selector is open, and the entry is still present. Cache writes may complete for a stale UI generation because they remain useful. Queue keys prevent duplicate work in the same generation. One job at a time preserves frame stability and the existing renderer assumptions.
 ## 9. Overlay, popup, and dialog integration
 - `StagePlacementOverlay.apply_style(style: Dictionary)` receives resolved guide/valid/invalid metrics. Existing public setters and screen-constant line math remain intact.
 - The three terrain ghost modulates come from `overlays.valid`, `overlays.same_type`, and `overlays.invalid`; classification values and commit rules do not change.
 - `StageDirectorVisuals.apply_style(style: Dictionary, fonts: Dictionary)` receives already-resolved sizes/colors/fonts. Keep `set_style(Dictionary)` as a legacy wrapper through Phase 7 tests.
 - All PopupMenus use `popups.action_menu`; Accept/Confirmation/File dialogs use `popups.dialog`; `AssetSelector` uses `popups.asset_selector`.
 - `_apply_popup_theme()` remains temporarily as a wrapper around `SandboxTheme` so existing direct tests do not break.
 - Tooltip positioning continues clamping to the visible viewport. Palette dock bounds are also treated as UI, so a tooltip never becomes a valid world drop region.
 ## 10. Future speech customization contract (blueprint only)
 When implemented in a later phase, a flat queue action will optionally carry one nested visual object:
 ```gdscript
 {
    "type": "speak",
    "text": String,
    "duration": float,
    "stop_current": bool, # optional, existing
    "visual": {           # optional; absent means theme defaults
        "font_preset": String,
        "size_preset": String,
        "color": String,       # HTML RGBA
        "bubble_style": String # standard/yell/thought/whisper
    }
 }
 ```
 Rule actions will store the same `visual` dictionary under their existing `params`. `ActionRegistry.to_rule_action()`/`from_rule_action()` will copy it unchanged, `StageSceneIO` will validate known scalar fields while preserving absence, and `SpeechBubble.show_text()` will eventually accept a style dictionary. Unknown preset/style IDs must resolve to theme defaults rather than invalidating the action.
 Phase 7 only reserves the theme IDs and supplies the reusable controls. It deliberately does not modify save files or runtime speech behavior.
 ## 11. Compatibility and migration
 - Theme schema `1.0`, missing version, and `2.0` are accepted. Unsupported future major versions warn and use recognized keys plus defaults.
 - Legacy aliases are applied before validation:
  - `mode_colors.edit_accent/direct_accent/play_accent/guide_line` → `mode_colors.edit/direct/play/guide`.
  - Existing flat `fonts.*_font_size` keys → matching `fonts.sizes.*` keys.
  - `fonts.action_popup.{size,bold,italic}` → `fonts.sizes.action_popup` and `fonts.flags.action_popup_*`.
  - Existing bold flags and `assignment_badge_radius` retain their current meaning.
 - A v2 key wins when both v2 and its legacy alias exist.
 - No automatic write-back of user theme files occurs.
 - Existing `user://sandbox_settings.json` values win over theme defaults. If a settings key is absent, the loaded theme value—not the old hard-coded constant—is used.
 - `.scene` serialization remains byte-contract compatible because Phase 7 changes no scene payload fields.
 - Existing public stage signals (`mode_changed`, `object_placed`, selection/deletion signals), `AssetSelector` signals, placement IDs, and action dictionaries remain unchanged.
 - Existing private test-visible fields remain present. `_palette_buttons` values remain `Button`-compatible.
 - Missing emoji/custom fonts degrade to `ThemeDB.fallback_font`; labels stay usable even if a glyph renders as a fallback box.
 ## 12. Delivery phases and acceptance criteria
 ### 7.1 Theme service and schema
 - `SandboxTheme` loads the committed v2 file and produces complete resolved values.
 - Missing/malformed files, invalid individual keys, and missing font paths never abort startup.
 - v1 aliases reproduce current sizes/colors.
 - Font/style/theme caches reuse resources; caller mutation of one returned stylebox does not affect another.
 - Existing grid setting precedence is preserved with the corrected theme fallback for missing settings keys.
 ### 7.2 Chrome and mode polish
 - Mode segments are one exclusive group with clear active accent and keyboard focus.
 - Frame, badge, and status bar update immediately in EDIT/DIRECT/PLAY; the frame uses each mode color in every mode.
 - Existing cursor, tooltip, target trajectory, status coordinate, and Escape behavior pass unchanged.
 - At 1280×720, top/bottom chrome and the palette do not cover each other; at smaller windows, the palette scrolls instead of overflowing.
 ### 7.3 Reusable widgets
 - All four controls configure from the theme contract, rebuild safely, emit exactly once per user choice, and expose their selected value.
 - Empty/malformed preset arrays fall back safely.
 - Every interactive item has keyboard focus and a minimum 44×44 target.
 ### 7.4 Palette, selector, and thumbnail cache
 - Six registry-driven graphical cards appear only in EDIT and preserve `_palette_buttons` state semantics.
 - Click-arming, modal Prop/Stickman selection, repeated placement, RMB/Escape cancellation, and mode transitions behave as before.
 - Dragging a palette card over the stage places exactly one item; release over UI/cancel places none and leaves no ghost.
 - The selector retains pagination, dimming, Browse/Refresh, generated previews, and click selection.
 - Cached textures are reused from memory/disk, duplicate jobs are suppressed, and stale async completion never updates a closed or repopulated selector.
 ### 7.5 Popup/overlay consistency and regression
 - Popup menus, dialogs, panels, selector cards, tooltip, terrain guides, ghosts, and action trajectories use the resolved theme.
 - Terrain painting still uses template AABB stride, Bresenham cells, three classifications, Shift axis lock, and skip-on-conflict commits.
 - Queue/rule/action editor behavior and font APIs remain compatible.
 - No changes occur to speech rendering or saved action schemas.
 ## 13. Validation strategy
 ### Headless tests
 Run the new suites plus the regression suites most directly touched:
 ```powershell
 & "C:\Godot4\Godot_v4.7.1-stable_win64_console.exe" --headless --path "C:\Godot4\stickman" --script res://tests/test_phase7_theme.gd
 & "C:\Godot4\Godot_v4.7.1-stable_win64_console.exe" --headless --path "C:\Godot4\stickman" --script res://tests/test_phase7_widgets.gd

 & "C:\Godot4\Godot_v4.7.1-stable_win64_console.exe" --headless --path "C:\Godot4\stickman" --script res://tests/test_phase3b_library.gd
 & "C:\Godot4\Godot_v4.7.1-stable_win64_console.exe" --headless --path "C:\Godot4\stickman" --script res://tests/test_phase3b_ui_fixes.gd
 & "C:\Godot4\Godot_v4.7.1-stable_win64_console.exe" --headless --path "C:\Godot4\stickman" --script res://tests/test_phase3c_bugfix.gd
 ```
 Run `--check-only` on every added/changed `.gd` script before those suites. Tests should exercise public methods/signals where possible; source-text assertions are only a last resort for engine behavior that cannot be driven headlessly.
 ### User verification in Godot (spec-pipeline hand-off)
 After implementation and green headless tests, stop and ask the user to verify:
 1. Resize the Sandbox Stage from 1280×720 down to a small window and confirm chrome/palette remain usable.
 2. Switch all modes and confirm frame, badge, segment, status, cursor, and visibility changes.
 3. Click-arm and drag-drop each card type; cancel by UI release, RMB, Escape, and a mode change.
 4. Open Prop and Stickman selectors twice to confirm thumbnail reuse and no visible stale updates.
 5. Exercise Direct-mode Walk To and rule targets to verify tooltip/trajectory/reticle layering.
 6. Terrain-paint empty, same-type, and conflicting cells with and without Shift.
 7. Open Speak/Wait/Rename, queue/rule editors, and context menus to judge font size, contrast, and emoji fallback.
 Do not update README/project documentation until the user explicitly confirms the feature works.
 ## 14. Design decisions and trade-offs requiring approval
 1. **Keep the Sandbox UI code-built.** This minimizes churn in a 4,000-line controller and preserves existing test-visible fields. Replacing it with a complete UI scene is deferred.
 2. **Use a dedicated theme service, not raw dictionary reads or a JSON-to-Theme singleton.** The stage owns one instance, making tests deterministic and avoiding global state; a cached Godot `Theme` still supplies normal Control inheritance.
 3. **Use custom card pointer capture for world drops.** A full-screen Control drop target risks intercepting the existing Node2D world input stack. Drag placement is intentionally one-shot; click placement remains persistent.
 4. **Show the mode frame in all modes.** The plan says it reflects the active mode; the current implementation shows it only in DIRECT. Phase 7 changes that behavior.
 5. **Reserve but do not implement speech customization.** Theme presets and reusable controls land now, while action persistence/runtime rendering stay unchanged until a dedicated speech phase.
 6. **Serialized, cached thumbnail work is preferred over threading.** It is safer with Godot viewports and already matches the working architecture; memory caching and generation tokens address the actual stutter/stale-update risks.
