Task type: bug fixing

Read:
- AGENTS.md
- docs/ai/bevy-debug-playbook.md
- ai/context/project-context.md

Then:
- restate bug
- list top 3 likely root causes
- point to exact file/section likely involved
- propose smallest fix first
- show verify commands
- if evidence weak, say what to inspect next
- keep Bevy 0.18.1 APIs only
