/* ══════════════════════════════════════════════════════
   GROVE FOUNDATION — TYPOGRAPHY TOKENS
   Three-font stack:
     · Instrument Serif — display headlines, card titles (italic = amber emphasis)
     · Fragment Mono    — labels, nav, metadata, eyebrows, code
     · DM Sans (300–600) — body text, descriptions
   Type scale is fluid (clamp). Mono labels run small with
   wide tracking (0.1–0.25em). Body is 15–17px / 1.75–1.85.
