/* cancion.css — Chrome for standalone song ("cancionero") pages under /canciones.
   Ported from the sibling "cancionero" project's assets/site.css: header, title
   bar with the transpose/zoom/hide-chords controls, teleprompter, and the chord
   diagram modal. The song text itself (.letra/.sobre/.c) is styled encapsulated
   inside <song-sheet>'s shadow root (see ../../shared/song-sheet.45c18c885c.js) — this file
   only styles the page chrome around it. Self-contained (own tokens) so this
   page doesn't depend on site.css. */
