   Brand: blue #306EFE · azure #0293FB · violet #7A3FF0
          pink #FD6EF2 · white #FFFFFF · ink #171726
   Dark theme is the base. Gradient is an accent, not a fill.

   Motion rules used throughout:
   · interactive transitions 180–600ms, ease-out
   · ambient/background loops 8–24s
   · only transform / opacity / filter are animated
   · everything collapses under prefers-reduced-motion
