   SERENITY DESIGN STUDIO — DESIGN SYSTEM
   Token system derived from the studio's mark (oxide red #A2262D) plus a
   warm, concrete-and-linen architectural palette. Display face is Fraunces
   (a serif with real optical weight, used sparingly for editorial titles),
   body face is Manrope, and a monospace face (Space Mono) is reserved for
   "drawing annotations" — the small coordinate/figure labels that behave
   like notes on an architect's plan rather than decorative numbering.
