/* ===========================================================================
   FTM Vocal — Design System + Widget Styles

   All colors and fonts reference the freethemusic theme's tokens first, then
   fall back to the same values hard-coded. If the theme updates its tokens,
   this plugin's widgets update automatically — no CSS edits needed.

   Architecture mirrors ftm-music-theory.css so the two plugins look identical
   when rendered on the same page.

   ftm-songbook bundles — keep these in sync if Prequel is ever updated. */
