## Documentation

- [ ] I updated the root README for user controls, run commands, or troubleshooting changes.
- [ ] I updated `docs/editor/` for editor workflow or feature-design changes.
- [ ] I added or updated an ADR for architecture, policy, scene format, rendering path, PIE semantics, settings schema, or netcode decisions.
- [ ] I indexed new documentation in `docs/README.md`.
- [ ] If this is Jackdaw-inspired work, I identified it as design-inspired, API-inspired, or code-derived.
- [ ] If this includes copied or closely translated source, I included source URL, upstream commit/release, license compatibility notes, and required file-level notices.
