/* The Family Cloud design language, ported from the design handoff.
   (design bundle: family-cloud-apps/design; token source of truth:
   family-cloud-apps/contract/tokens.json)

   Rules that shape everything here:
   - Dark is the primary theme; light has full parity.
   - Gold = progress/premium, blue (the accent) = action, green = success.
     Flat brand fills are FILL-ONLY on dark; text/icons use the lifted pair.
   - Glass exists only on floating chrome; content panels, toasts and dialogs
     are opaque. Text is never a child of a distorting filter.
   - Plex Sans is content; Plex Mono is every number, size, speed, status word
     and kicker. Max weight 600. One springy easing curve for all motion.
   - Status is shape + word + motion, never colour alone. */
