/* ==========================================================================
   d4vinder shared design system
   One stylesheet for the studio site and every app subsite. Apple-inspired:
   clean surfaces, San Francisco system type, generous space, hairline rules,
   a single accent colour per site that each subsite may override.

   Override the accent per app by setting --accent on :root or [data-app] in a
   small local stylesheet loaded after this one. British English throughout.
