/* ============================================================================
   Devalo cinematic template , styles.css
   ----------------------------------------------------------------------------
   WHY this file is structured token-first: brand-tokens.json is the single
   source of truth. Every colour / type / radius / space value below is a CSS
   custom property seeded from that file. A client fork re-skins the whole
   property by swapping the token values in this :root block , nothing else.
   No raw hex / px is written in component rules where a token exists (the
   token-or-die discipline); the only bare literals are 0, 1px hairlines,
   %/vw geometry, and effect-specific rgba() glow alpha.

   Concept: "considered craft, layer by layer" , a dark, engineered stage.
   Surfaces are thin translucent panels with cyan hairlines (engineered, NOT
   frosted glassmorphism , no decorative backdrop-blur), flat by default,
   depth expressed through parallax planes and hairline precision.

       pre-divided by the size-adjust so the effective box matches Geist exactly.
