Implement speech style toolbar live-edit refinements and whole speech show controls

- Added a new specification for the speech style toolbar live-edit, detailing immediate style application, scoped effect demonstration, and hover feedback.
- Introduced refinements to the speech style toolbar, including improved chooser sizing, exclusive stage editing during speech composition, and removal of redundant controls.
- Documented new stage controls for managing how the whole speech shows, including options for bubble arrangement, word appearance, and bubble motion.
- Created a new log file for speech padding syntax to track engine versioning.

+## 1. Kid-Friendly UI Guardrails (10-Year-Old Persona)
+
+* **Touch & Click Target Rules:**
+  * Minimum pointer hit-target: **44×44 logical pixels** (never build tiny 16px/24px buttons).
+  * Control heights (buttons, dropdowns, rows) must obey `button_min_height` tokens from the theme.
+
+* **Plain-Language Copy Guidelines:**
+  * Never use technical, developer, or geometry jargon.
+  * Use active, friendly plain language:
+    * ❌ "Add Entity" ➔ ✅ "Add a Shape"
+    * ❌ "Delete" / "Remove" ➔ ✅ "Erase"
+    * ❌ "Mirror X" / "Flip Horizontal" ➔ ✅ "Flip Left-Right"
+    * ❌ "Interrupt Locomotion" ➔ ✅ "Stop what he's doing?"
+
+* **Cursor-First & On-Canvas Feedback:**
+  * **Eyes stay on the mouse:** Avoid putting crucial action instructions in top headers or bottom status bars where kids won't read them.
+  * **Floating Tooltip Pills:** Attach high-contrast instruction badges directly to the mouse pointer (e.g., `🚩 Click to set walk target`).
+  * **Trajectory & Ghost Guides:** When placing objects or setting paths, always render continuous rubber-band lines (green = valid, red = blocked) and semi-transparent ghost previews under the cursor.
+  * **Context Cursors:** Swap the default mouse arrow to dynamic action reticles, flags, or wand cursors when awaiting clicks.
+
+* **Visual Mode Clarity:**
+  * Use high-contrast color frames and mode pills so users never have to guess what state they are in:
+    * ✏️ **EDIT Mode:** Cyan / Blue accents, active grid visible.
+    * 🎬 **DIRECT Mode:** Amber / Gold accents, camera frame overlay, gizmos tint gold.
+    * ▶️ **PLAY Mode:** Green accents, grid hidden, clean viewport preview.
+
+## 2. Godot 4.7.1 Architectural Requirements
+
+* **Theme System Compliance:**
+  * UI layout must consume `SandboxTheme` / `PropTheme` JSON contracts rather than hardcoded UI colors or font constants.
+  * Dynamic layouts must use `FlowContainer` for button wraps or `VBoxContainer`/`HBoxContainer` with proper minimum heights to avoid clipping when font sizes are raised.
+  * Dialogs and popups must explicitly receive `theme.control_theme()` to respect window borders.
+
+* **Accessible Inputs:**
+  * Prefer simple explicit buttons (e.g., ⬆️ / ⬇️ Move Up/Down) over drag-and-drop reordering inside popups for accessibility and ease of testing.
+  * Always provide prominent, clickable `[X Cancel]` buttons on active workflows so users don't need to know the `Esc` key.
+
+## 3. Pipeline Output Protocol
+
+When invoked during Phase 0a (UI/UX Proposal & Alternatives):
+1. Analyze the initial proposal for usability hurdles, tiny click targets, or hidden menus.
+2. Pitch 1 to 3 alternate visual/interaction approaches (e.g., compare floating cursor badges vs. top notification bars).
+3. Mark your recommended choice with [Recommended] and ask up to 3 simple clarification questions.
+4. STOP and wait for user feedback.
+
+When invoked during Phase 0b (UI Spec Generation):
+Output a structured spec covering:
+* Control Layout & Node Structure (Containers, sizing rules, button groups)
+* Theme & Color Tokens (Active state colors, badge accents)
+* Cursor & Canvas Feedback (Floating labels, ghost markers, trajectory lines)
+* Kid-Friendly Copy Map (Exact string replacements for all visual labels)
