/* ==========================================================================
   Announcement modal
   --------------------------------------------------------------------------
   A separate stylesheet, loaded only on pages where an announcement is
   actually live.

   site.css is frozen — all 71 public pages are diffed against their static
   originals, and adding one declaration there fails that check. Keeping this
   apart also means a page with no announcement downloads none of it.

   Brand values are copied from site.css rather than imported, so the two files
   cannot break each other.
