/* ==========================================================================
   SOUND ALCHEMISTS — Audio di Mix & Master: player dei lavori e prima/dopo

   Due componenti, entrambi generati da JavaScript:
     .player  (assets/js/player.js)  sezione #work: card "now playing",
                                     elenco brani, riga Spotify, incorporato
     .ab      (assets/js/ab.js)      sezione #ab: confronto BEFORE / AFTER

   .player e .ab sono solo contenitori; la card vera è un figlio, perché è la
   card a portare data-rv (il reveal non deve toccare il contenitore).
   Solo variabili di tokens.css: la pagina è .theme-petrol e i colori
   cambiano da soli.
