Troubleshooting
Check behavior before surface.
- If the material is missing, confirm the registry-installed shared and component CSS files are imported once.
- If interaction differs, preserve this contract: Space toggles; read-only remains focusable without changing.
- If assistive output differs, preserve this semantic foundation: A real checkbox inside a labelled 44px target.
- If dark, RTL, or reduced-motion behavior is missing, verify the nearest theme, direction, and media-query boundaries rather than adding page-local overrides.
