   Signature: the anamorphic flare streak — a horizontal blue-cyan glow line,
   the one recognizable optical artifact of anamorphic cinema lenses. It marks
   focus, active state, and the single load-in animation. Everywhere else,
   the UI stays quiet: black canvas, hairline dividers, engraved-metal type.
