   MADAXONE — Design Tokens
   Palette:  near-black graphite ground, brass/gold accent (film & lens
   world, not the generic terracotta/acid-green defaults), warm off-white
   text. Type: Fraunces (display serif, editorial/fashion register) +
   Inter (body) + IBM Plex Mono (timecodes / structural labels).
   Signature: film timecode system (HH:MM:SS:FF) used as the structural
   numbering device throughout, plus letterbox bars on the hero —
   both drawn directly from the agency's own medium (video production).
