/* ============================================================
   Santino GTC Decor / Design system v4 "Mineral Atelier"
   Reimagined with imagegen direction: denser, warmer, more premium.
   Type: Schibsted Grotesk (display/UI/body) + IBM Plex Mono (data)
         Fraunces / wordmark only (the sole serif)
   One accent: mineral champagne. Two roles only: labels + interactive states.
   Spacing tokens: 8 12 16 24 32 48 56 80 104
   Hard law: text never sits on imagery. Plates and hairline frames only.
   ============================================================ */
