/* public/css/public.css
   Shared styling for the two pages ordinary app users (not admins) see:
   the feedback form and the app-link redirect page. Same design tokens
   as admin.css (lifted from the app's own theme.ts) so every surface
   under this domain feels like one product - but its own file, since
   these pages don't share admin.css's sidebar/table/dashboard rules. */
