   Clean Apple/macOS-inspired, translucent and teal-accented. EB Garamond for authority, a plain
   system sans for interface text (the way Apple pairs a display serif
   with San Francisco for controls). Every color is a CSS variable so
   Settings → Appearance can rewrite it live, per user, from SQL.
