/* ============================================================================
   DESIGN LANGUAGE — "Nordic craftsman" (D24)
   One token sheet, two skins: the admin console (style.css) and the client
   portal (portal/portal.css) both draw ONLY from these variables.

   Voice: calm, solid, trust-first. Deep granite/spruce base, warm paper
   neutrals, one high-vis AMBER accent (the work-gear nod) used sparingly —
   primary actions, the quota bar, the active nav mark. Nothing dances while
   you're reading numbers.

   Type: Bricolage Grotesque (display — headings, wordmark, big numbers) over
   Hanken Grotesk (body/UI). Self-hosted in /static/fonts — no font CDN (GDPR).
   Spec: docs/business/05-design-language.md
