/* ================================================================
   CatSU Enrollment — Authenticated Application Layer
   ----------------------------------------------------------------
   Loaded after flat-theme.css, before landing.css.

   Scope: every authenticated surface (student, staff, admin).
   The landing page keeps landing.css and is excluded explicitly.
   The Certificate of Enrollment document (.coe-*) is never styled
   here; it must keep its printable appearance.

   Design notes
   - Warm paper canvas instead of blue-grey, so long forms read like
     a document rather than a dashboard.
   - Hairlines and one elevation level: no gradient bars, no glows.
   - Sora for headings, Plus Jakarta Sans for text, tabular figures
     for every number that can be compared.

   The COE is a fixed white-paper artifact, so it must look identical in

   title and letterhead, --success for the scholarship row) that flip to
   light values in dark mode, which would make dark text on white turn
   pale and unreadable. The document's own stylesheet is left untouched;
   we simply pin those tokens to their light values for the subtree.
