/* =============================================================================
   Resident portal (spec F). Loaded by views/layouts/portal.php after the F1
   design system (tokens, base, components) and before utilities, inside the
   `areas` layer so the cascade order in tokens.css holds.

   An 18 px base for older eyes: the root is 17 px, so --text-base (1.0625rem)
   is 18 px and every rem-sized control scales with it. Works at 320 px, at
   200 % zoom and without JS.
