- Added a new event-driven system for reactive storytelling, allowing rules like "When X happens, do Y." - Introduced TriggerArea class for placeable sensors in the stage. - Enhanced StickmanRig to emit signals for actions and arrivals. - Updated StageDirectorVisuals to render rules visually with labels and badges. - Modified StageSpawner to support spawning TriggerAreas. - Improved text baseline calculations in speech bubbles and rule labels. - Added tests for text baseline fixes to ensure proper rendering. - Documented the implementation plan for Phase 4 in PHASE_4_TRIGGER_EVENTS.md. - Created a polish plan for Phase 4 in PHASE_4b_POLISH.md.

## PropBlock - Reusable dynamic vector prop (RigidBody2D).
|
|
##
|
|
## A root RigidBody2D with three children built in code — a Polygon2D (interior
|
|
## fill), a Line2D (crisp vector outline, round joints/caps), and a collision
|
|
## node: a CollisionPolygon2D with BUILD_SOLIDS for polygon props, or a
|
|
## CollisionShape2D with a CircleShape2D for circle props. Fully @tool: exported
|
|
## properties update the children live. A material preset selector sets mass,
|
|
## friction/bounce (PhysicsMaterial), and themed visuals.
