   MOTION — R-041 LOCKED (Brand Book §15).
   Product UI micro-interactions: 160–220ms. Motion is functional and
   restrained; it reveals clarity rather than creating spectacle. No bounce,
   no spring, no looping decorative motion, no glow/pulse, no parallax, and
   motion is never required to understand status or sequence.
   prefers-reduced-motion support is mandatory.
   (Marketing reveals of 300–500ms are out of scope for Product UI.)

/* Reduced-motion support is mandatory (R-041 §15) and is enforced here on the
   consumers rather than by redeclaring the duration tokens. Every animation
   and transition is neutralised, including the Button spinner keyframes, and
   the four --duration-* tokens keep their canonical 160/180/200/220ms values
   in the extracted token set instead of being overwritten with 0ms.
   Equivalent non-animated states are preserved; no meaning depends on motion. */
