/* ===========================================================
   SHARED PAGE FURNITURE
   Extracted 3 August 2026 from content.css, health-safety.css,
   module-page.css and timesheets.css, which each carried an
   identical copy of everything below.

   It lives at the end of core.css rather than in a page
   stylesheet because core.css loads first and none of the
   page stylesheets set these properties, so the cascade result
   is unchanged. The .pf-hero rules are descendant-scoped, so
   pages without a .pf-hero are unaffected.
