/* Gully ID UI: the ONE token + motion file shared by the landing (/), the sign-in card (/login and the other
   shell pages) and the Gully Wallet. Night ground (W2 Night, Gully ID brand kit v1 dark theme): every surface,
   line, text, accent, radius, font and button style of the three surfaces comes from here, so landing -> sign in ->
   wallet reads as one product. Page stylesheets only map these --ui-* tokens to their own names.
   Kit colours: cyan #00F7FC (mark, primary action on night), gold #F9AE1B (secondary accent), night #05080D.
   Motion: every keyframe runs only inside (prefers-reduced-motion: no-preference); without it the static styles are
   the finished state. CSS + WAAPI only (CSP script-src 'self'). */
