   Durga Aarti — interface layer

   The temple — its doors, lamps, bells and sanctum — is rendered in WebGL
   (scene3d.js). What sits over it here is kept to the language of the
   place: Garamond set like an old temple plaque, brass hairlines, a lotus
   divider, and buttons that are plates of brass rather than app pills.

   Performance: nothing here uses backdrop-filter. A blurred panel over a
   canvas that repaints every frame re-blurs every frame, and on low-end
   phones that alone cost more than the 3D scene. The only looping
   animations (diya flicker, button shine) are transform/opacity only.
