/* True Vision Camera — styles
   Token system follows the aesthetic research digest: one hue + one chroma drive a perceptual
   (oklch) scale; dark mode is its own token set (tinted base, surfaces rise in lightness,
   halation-safe text, lighter/lower-chroma accent); elevation on dark = light ring + ambient shadow;
   type on a 1.25 modular scale with optical sizing; motion 100–300 ms, ease-out in / ease-in out,
   transform + opacity only; few backdrop-filter surfaces. */
