/* ============================================================================
   RC GARAGE · MULTIDRONE  —  TEMA "MEDIODÍA"  (v1 final, drop-in reversible)
   ----------------------------------------------------------------------------
   Reskin claro: cielo con nubes + tráfico, tarjetas de cristal por estado,
   controles de cabina (metal azulado, encendido verde fósforo) y tablilla
   split-flap en los títulos.

   ACTIVAR  -> en index.html, DESPUÉS de tu CSS actual:
       <link rel="stylesheet" href="css/estilos.css">          (el tuyo)
       <link rel="stylesheet" href="css/mediodia-theme.css">   (este, el último)
       <script defer src="js/mediodia.js"></script>            (cielo + tablilla)

   REVERTIR -> borra (o comenta) esas dos líneas. Nada de tu código cambia.

   No toca la lógica ni la API: solo redefine los tokens que ya usa tu app
   (--bg-*, --fg-*, --accent...) y decora las clases existentes.

   PENDIENTE de afinar con tu index.html + CSS: cabecera fija, barra de
   navegación y modales (sus clases no las conozco todavía).
