/* Global reduced-motion guard (the settings/tools strategy 13 inherits).
   Two levers: (1) --motion-scale → 0 collapses every token-driven transition;
   (2) a blanket clamp settles infinite DECORATIVE loops to ONE run at their
   end-state (animation-iteration-count: 1) instead of freezing them mid-frame
   — the audit's caveat (a naive 0.001ms blanket freezes the marquee mid-scroll
   and hides text). NOTE for chunk 13: TRANSFORM-based loops (marquee,
   scanline-sweep, radar-sweep) end translated away, so their components must
   add an explicit `animation: none` + static-position opt-out under this query
   — a blanket guard cannot safely settle a translate loop. */
