   ATMOSPHERE — static conic vignette + film grain

   gets an identical layer.

   Brand reference:
     --opacity-grain          .022   (tokens/rendering-hierarchy.css)
     --opacity-grain-reduced  .012   (under load pressure)
     --z-tier-atmosphere      3      (tier 1, "Atmosphere")
     Tier 1 spec: will-change auto (static), grain is an additive blend.

   Per FORM_UI_DOCTRINE both layers are STATIC — no animation, no
   cursor coupling, no pulsing. Atmosphere, not a HUD.
