/* ============================================================
   DESIGN TOKENS - locked from the approved art + ui-ux-pro-max
   "iOS notification / fintech dark" system search.
   Palette: cool blue on black, pulled from the multi-exposure
   photo's own blue tone. Cards: off-white iOS-notification cream,
   near-black card text (matches the baked avatar exactly).
   Type: Inter (closest bundleable stand-in for the SF-Pro
   iOS-notification look; system-font stack is banned as the
   visible face, so it is fetched, not defaulted).
   Spacing scale: 8 / 12 / 16 / 24 / 32 / 48.
   Radius: 22px (card), 14px (chip) - iOS-style continuous corners.
   Motion: card slide-down-in / slide-right-out, one idiom reused
   everywhere a card enters or leaves.
