   AUREL — aurel-auteur (direct register) · stylesheet
   A lit printed ledger. Palette + type committed in design/COMMIT-SHEET.md.
   Owner direction (2026-10-08b): brand/editorial craft — Pentagram/Porto Rocha/
   Collins typographic rigour, Aesop/Apple/Linear calm, Buck/Ordinary Folk motion.
   Rules in force: hierarchy carried by DECISIVE display sizes; one rigorous grid
   across all 7 scenes with deliberate asymmetry (never default centring); paper +
   ink + ONE cyan used as punctuation, never decoration; motion choreographed and
   purposeful. No WebGL — type and motion carry the film.
   Build order (auteur direct.md phase 2): foundation → hero → scenes → reveals
   → reduced-motion cut → mobile pass. This is that cut.
