  ReyDen family design system v3 (Direction B). Canonical file: ReyDen/src/styles/family.css.
  Copies in ReyTV, ReyUpload/frontend and ReyLink are byte-identical (node scripts/sync-family-css.mjs).
  Edit only here. Site-specific CSS goes in each site's own stylesheet.
  Dark only. Per-product accent comes from [data-product]; that block is GENERATED from family/products.json
  (node family/tools/gen_accents.mjs). Do not hand-edit between the GENERATED markers.
  Sections: 1 fonts / 2 tokens / 3 base / 4 type + layout / 5 buttons, forms, data / 6 shell / 7 hero frame /
  8 layered card + step card / 9 responsive + reduced motion / 10 steps rail / 11 living hero / 12 tilt / 13 ecosystem / 14 legacy v2 components.
