/* brand.css — RRRz, the brand surface (rrjjbb.com).
   One design system with ricrios.com: every size, space, weight and
   tracking value here is a PLATFORM token (css/platform/), and the type
   ROLES are the platform's own — the serif divergence was retired
   (2026-08-24) because two faces made two platforms, and the whole
   point is one. If a value in this file is a literal, it is a defect. */
