- Camera assets get width/height properties; play mode renders only the camera frame (letterboxed, masked, culled) and nothing without a camera - Remove demo arrow-key/camera-follow systems from play mode - Clip world and gizmos to the viewport (selection frame no longer leaks over the left panel) - Blur focused widget on pointerdown outside it so inspector edits commit before selection changes - Separate objects/overlay layers so camera symbols always render on top - Add tools/seed-demo.mjs for reproducible E2E runs Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
