/* ─── MASTER KEY · visual identity v2 — the engraved brass atelier ───────
   Not a dashboard: an instrument. Fraunces display type, open editorial
   sections numbered like plates in a folio, hairline gold rules, one huge
   engraved °7 sigil turning behind everything. Gold is the brand (the key,
   the 6th chord, rest). Three dim7 families own three semantic colors:
   fam0 (A C Eb F#) = jade · fam1 (Bb Db E G) = rose · fam2 (B D F Ab) = cyan
