/* whatelse?
   Dirección: «el ticket de la compra». El ticket es el único adorno; el resto es papel y tinta.
   - Una sola familia para la interfaz (Bricolage Grotesque) y una mono solo en el ticket (Martian Mono).
   - Listas como listas: una superficie por sección, filas separadas por una línea fina, sin sombras.
   - Precios siempre alineados a la derecha con cifras tabulares.
   - Oscuro por defecto; el claro se activa con data-theme="light" (lo pone prefs.js).
   - Radios con jerarquía: 16px paneles, 10px controles, redondo solo en casillas, avatares y chips. */
