/* ============================================================
   Guidefastly — "Doorstep" design system (v1, 28 Jul 2026)
   Replaces "First Light". Tokens are exact per STRATEGY-UNIQUENESS §2 —
   verbatim, per Leo's decision (28 Jul). Known measurement, accepted by Leo:
   --accent-text #C44D14 is 4.40:1 on --bg (4.75:1 on --surface); the contrast
   script reports that single pair as spec-pinned instead of failing.
   Budget: this file ≤10KB. Fonts: two self-hosted variable woff2, 76KB total.
