feat: add prefers-reduced-motion and prefers-contrast media queries (#5122) * feat: add prefers-reduced-motion and prefers-contrast media queries - Integrate OS prefers-reduced-motion into existing JS toggle system: when OS preference is active, force reduced_motion on and disable the UI checkbox with an explanatory tooltip - Add body.reduced-motion CSS rules for hardcoded animations that bypass the --animation-duration variable (text_segment fade-in, dragover pulse) - Add prefers-contrast: more media query for enhanced focus outlines Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * Support translating title text * Use duration variable * Removed stream fade-in override * Combine hi-contrast selectors --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com> Co-authored-by: Cohee <18619528+Cohee1207@users.noreply.github.com>
