/* =========================================================================
   Matrix — Service Bulletins & Safety Notices
   Built from Figma: 6582_MTRX_PublicServiceNoticeandBulletinPage (14202:1382)

   Hand-written CSS rather than Tailwind utilities on purpose. The theme
   compiles Tailwind through Vite, so any new utility class would only exist
   after `npm run build` — this has to work as a straight cPanel file upload.

   Everything is namespaced under .mtrx-notices so it cannot leak into the
   rest of the Aedificus Primaris theme.
