   This is the FLOOR. Customise the accent token below per the student's
   colour pick. Do not regress on motion, micro-details, or section structure.

   Token order:
   1. Colours — strict per brand-dna.md (white bg, near-black text, single accent)
   2. Type scale — Inter only, mobile-first, scales up at 1024px
   3. Spacing — 8px multiples
   4. Motion — cubic-bezier(0.16, 1, 0.3, 1) [expo-out], 600–850ms reveals

   See `design-reference/quality-bar.md` for the pre-ship checklist.
