   2. LOGOS — Broadcast / Streaming Pro Layout
   -----------------------------------------------
   Principios UX/UI aplicados:
   · Eliminación de contenedores con fondo (anti-pattern)
   · Distribución óptica con espacio negativo generoso
   · Alineación vertical centrada
   · Separador sutil entre logos (jerarquía sin competencia)
   · Sombra drop-shadow sutil para legibilidad
   · Transiciones premium para hover
