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: No component-specific keys.
- If assistive output differs, preserve this semantic foundation: Status semantics are opt-in through the visible or accessible label.
- If dark, RTL, or reduced-motion behavior is missing, verify the nearest theme, direction, and media-query boundaries rather than adding page-local overrides.
Implementation decisions
When to use Spinner
Use a spinner for a short indeterminate operation when no honest completion fraction exists. Pair it with text that says what is being attempted and update that status when the operation succeeds, fails, or can be retried. Disable only the controls that truly conflict. Test instant completion, long waits, cancellation, reduced motion, screen-reader announcements, and route changes so loading feedback never traps a customer.
