/* =====================================================================
   FX - the visual layer over components.css.
   Everything here is presentation: gradients, depth, motion and the
   celebration overlay. It changes no layout contract a view relies on,
   and every animation sits behind prefers-reduced-motion (tokens.css's
   blanket reduce rule then collapses anything left over).

   Colour stays inside the brand: Iris carries everything, and the nine
   cause hues below are used only as small accents (a dot, an icon tile,
   the top edge of a tile), never as surfaces, so purple stays the loudest
   voice as PRD section 5.1 asks.
