- Public registration APIs: course signup, event registration, membership application
- Document generation: PDF member cards, Excel reports, HTML labels
- Landing page: real Com.BISS content (no filler text)
- UX audit fixes: AccountNotFound component, shared status badges, confirm dialog,
  pagination, duplicate heading removal, emoji→badge replacement, a11y fixes
