   9. Announcements — page & cards

   Loaded after style.css in head.php, so it can override any matching rule
   from the global stylesheet via cascade order.

   The detail view is a real `.bottom-sheet` (assets/components/bottomSheet.css)
   and is NOT styled here. Earlier versions of this file contained a parallel
   `.popup-overlay` / `.popup-content-box` definition — that block was removed
   once the detail view migrated to the canonical sheet component.
