/* VocaVibe Realtime — shared styling for the public documents.
   Editorial rather than boxy: the colour lives in the hero, the text sits on
   white, and notes are a rule instead of a panel. Palette and the light display
   weights follow the printed manual (docs/manual_he.html); the gradient and
   radii follow the app (lib/theme/vv_tokens.dart). */
