/* ui.css — rocola's one design system, shared by every page.
   Identity: paper, ink and one red; each venue adds its own colour for its name. Geist stands in for Söhne until a
   licence is bought; IBM Plex Mono carries data, times and numbering. Small tracked mono labels are the brand's
   way of naming a block (AHORA, SIGUE). Pages are paper; the player is ink. Shape: controls are pills, surfaces
   12 px, artwork 6 px. Motion: 180 ms on state changes, none under reduced motion. */
