/* ============================================================================
 * COSGROVE — LANDING DESIGN SYSTEM · Caret identity v1.1
 * Source of truth: cosgrove-brand.vercel.app/BRAND.md (+ /assets/cosgrove.css)
 *  • Serif speaks (Newsreader), sans operates (Inter), mono reports (Plex Mono).
 *  • Flat ink on paper: hairlines and space create hierarchy. No shadows.
 *  • One green: Cosgrove green #07A488 is both the brand accent and the
 *    healthy/verified/live color. Bright #6BFFDC only as CTA fill / on ink.
 *  • Legacy token names (--mint, --ok, --brand-pink) are kept as aliases so
 *    the page's bespoke styles resolve to brand values.
