/* ============================================================
   Uniqcret — "Choose Your Character" page (gpts.html)
   Layered on top of main.css; reuses its tokens (--bg, --ink,
   --accent, --glass, --line, --radius, fonts) so theme + lang
   toggles Just Work. House aesthetic: near-black canvas, ONE
   accent hue, glass cards, big editorial type, motion that
   ARRIVES (rise + fade) — no bounce/spin. All animation is
   transform/opacity; reduced-motion gets instant final states.
