/* Semantic Retrofit Group A Batch 5, 2026-09-08: migrated to
   --lib-surface-brand-primary (the real, existing Color Role Contract
   role for exactly this case -- a background/fill intentionally tinted
   with brand primary, same value as --lib-color-primary). Real intent
   confirmed against the family's own sibling primitives: Wave Divider
   and Diagonal Cut (also Dividers & Separators) both default their own
   section-transition fill to primary too -- a small colored ornament is
   this family's own established real pattern, not a neutral-gray rule
   like a plain <hr>. Zero real production consumers exist for this
   primitive to confirm otherwise either way (a real, disclosed finding,
   not assumed). */
