/* Estructura compartida por los tres skins alternativos (Retro, Liquid
   Crystal y Night Mode): los tres reemplazan el Now Playing moderno por
   la misma "pantalla física" (banda, dot-matrix de 3 líneas, analizador
   ancho) — solo cambian los colores/tipografía, no el layout. El layout
   moderno (.now-playing-modern) y esta pantalla (.retro-display/
   .spectrum-card) son hermanos dentro de .now-playing-card
   (display:flex; flex-direction: column en app.css); acá se decide cuál
   se ve y en qué orden. El transporte (prev/play/next o rewind/play/
   forward) es el mismo elemento en los cuatro skins, solo se reordena.
   Los colores de cada skin viven en este archivo (Retro), theme-lcd.css
   (Liquid Crystal) y theme-night.css (Night Mode). */
