Composer and form polish: mentions pick people from a popover, loading states use a spinner, polls can undo a vote without yanking you off the feed, and display names are length-capped at registration.
In the product
What members, moderators, and admins see
Composer and posts
- Mentioning someone in markdown opens a popover instead of raw handle guessing.
- Pinned posts refetch correctly after pin/unpin.
- Undoing a poll vote stays on the post; it no longer navigates the feed away.
Forms and identity
- Loading placeholders use the LoadingSpinner animation instead of static text.
- Registration enforces a maximum display name length.
- Cover-image upload describes the expected specs. Checkboxes in forms can render nested content.
- Community favicon buttons use the default variant. Group action menus are simpler to scan.

Housekeeping
- Old Skeleton theme files are removed from the UI library.
