/* ==========================================================================
   MONOFORM — design system
   Every tunable value lives in :root. Change it here, it changes everywhere.

   Foundation is the Monoform brand kit (Desktop/MONO/BRAND/):
     Black #000000 · Charcoal #1c1c1c · Off-white #f6f6f6
     Warm grey #d4d1cb · Monoform Orange #e94b28 (accents only)

   One deliberate deviation from the Canva kit: headings are League Spartan
   (the logo font) rather than Cormorant Garamond. Cormorant was chosen when
   Monoform sold cinematic media; a serif reads soft on a systems company.
   To revert, change --font-display below — nothing else needs touching.
