   Ntizar Design System — Pack THREE (v6)
   --------------------------------------------------------------------------
   Contenedores y HUD para escenas Three.js de la librería `three-scenes.js`.

   Classes:
     .nz-three                -> contenedor de escena (relative, rounded)
     .nz-three--hero | --md | --sm | --aspect-16x9 | --aspect-1x1 | --bleed
     .nz-three--glass-frame   -> marco liquid glass alrededor del canvas
     .nz-three--interactive   -> parallax sutil del canvas con el cursor
     .nz-three__canvas        -> el <canvas> (width/height 100%)
     .nz-three__hud           -> capa HTML sobre el canvas (z-index)
     .nz-three__badge         -> badge flotante (esquina)
     .nz-three__caption       -> pie de escena
     .nz-three__legend        -> leyenda de colores de la escena
     .nz-three__fallback      -> contenido estático si no hay WebGL
     .nz-three__fallback > *  -> se muestra solo cuando .is-fallback en el contenedor

   Contrato con three-scenes.js:
     - El script añade/remove `is-fallback` en el contenedor.
     - Con `.nz-three--interactive` el script escribe `--nz-tx/--nz-ty`
       (transform sutil del canvas, activado con data-nz-motion != "none").
