/* GoPoTa «fx» — the success film and the GOPOTA ceremony (see fx-ceremony.js and docs/MOTION.md).
   Every rule is scoped under html.fx: with the preview off this file changes nothing.
   Colour is brand tokens only; the six segments always have hard joins.
   Motion rules live under prefers-reduced-motion: no-preference; the only static addition is the
   coupon line in the completed GOPOTA block (server markup, visually hidden without fx). */
