   BIRO 404 — R11 Works section redesign lab (isolated)
   Three variants share this sheet, scoped by root class:
     .wl-a  Editorial Spotlight  (one dominant project, next peeks)
     .wl-b  Cinematic Stack      (full-width bands, mask reveal)
     .wl-c  Minimal Index + Preview (numbered list + big preview)
   Reuses the site graphite+amber token system. No homepage change
   until a variant is chosen. Reduced-motion removes transforms.
