REDUCED is snapshotted once at construction (src/core/threadText.ts ~146). Toggling the OS reduce-motion setting after mount has no effect until remount; the React hook only remounts on the explicit reducedMotion prop. Suggested: add a matchMedia('(prefers-reduced-motion: reduce)') change listener that updates the flag (and clean it up in destroy()).
Severity: Minor (accessibility)
