/* CreaIPTV — Panel lateral de canales y Menú principal */

/* ── Panel lateral de canales (rediseño "flotante") ──────────
   - Posición absoluta SOBRE el video (no empuja layout).
   - Despegado de los bordes (margen 14px top/right/bottom) para que
     visualmente flote, no esté pegado.
   - Fondo translúcido con blur fuerte → el video se ve detrás difuminado.
   - Borde sutil + sombra para que se sienta "encima" sin ser invasivo.
   - Mismo lenguaje de colores que las pills overlay. */
