/* CÓMO ESTÁ ORGANIZADO ESTE ARCHIVO
   · CSS escrito a mano, sin Tailwind ni compilación: funciona tal cual,
     también sin conexión. Las secciones 9, 10 y v7 se añadieron en
     versiones posteriores y amplían las anteriores.
   · VARIABLES (custom properties): los colores se definen una vez en
     :root (tema claro) y se redefinen en [data-theme="dark"]. Los
     componentes usan var(--bg), var(--text)… así el tema cambia todo
     a la vez con un solo atributo en <html>.
   · RESPONSIVE «de escritorio a móvil»: reglas generales primero y luego
     @media (max-width: …) para tableta (≤900px) y teléfono (≤640px, ≤400px).
   · ACCESIBILIDAD: foco visible, .sr-only (texto solo para lectores de
     pantalla) y prefers-reduced-motion (sin animaciones si el usuario
     lo pidió en su sistema).
   · Los atributos de estado (data-state, aria-selected, [hidden]) se usan
     como selectores: JavaScript cambia el atributo y el CSS el aspecto.
   
   TOKENS: «fichas» de diseño reutilizables (colores, radios, sombras).
   Cada formato tiene su color: Letra (azul verdoso), Acordes (ámbar),
   Partitura (violeta), también en los chips y botones. */
