Conversation
Single @media block injected via ROOT_TOKEN_STYLES collapses all 77 chat + a2ui motion sites to instant, with targeted static fallbacks for the six infinite-loop indicators. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Single-task TDD plan: failing spec → export ROOT_TOKEN_STYLES → add @media block → confirm pass → manual smoke → PR. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Single @media block injected via ROOT_TOKEN_STYLES collapses every transition/animation to instant under the user's OS-level "Reduce Motion" setting. Targeted overrides replace six infinite-loop indicators (spinner, typing dots, caret, welcome pulse, shimmer skeleton, debug pulse) with static fallbacks — frozen mid-loop reads as a bug. WCAG 2.3.3 compliance. No JS, no consumer changes, no new tokens.
