/* ---------------------------------------------------------------------------
   Shared stylesheet. Identical on every site; the brand colors are injected
   as --brand / --brand-dark / --accent from site.php.

   This file is the STRUCTURE. Each site's personality -- fonts, hero
   treatment, textures, motifs -- lives in its own assets/css/theme.css,
   which ships from sites/<domain>/ and loads after this file.
   Prefer editing a theme.css over editing this file.
