   GLOBAL VIDEO — Canvas fijo detrás de TODA la página

   Claves de la corrección:
   · min-width/height 100vw/vh con width/height: auto → el video
     cubre el viewport sin deformarse (más confiable que 100vw/vh)
   · transform: translateZ(0) → fuerza GPU compositing layer,
     garantiza que el browser aplique position:fixed correctamente
   · z-index: -9999 → bajo el threshold donde cualquier contenido
     normal (z-index: auto = 0) estará siempre encima
   · SIN <source> hijo — src directo es más simple y menos
     propenso a reflows durante la carga
