- muted text #9e9ec0 -> #727299 (contrast 2.6 -> 4.5 on white); tab labels 11px - map: chapter titles wrap to two lines instead of being cut off - reduced-motion respected (MotionConfig + CSS), focus-visible ring, no pull-to-refresh, short vibration on correct/wrong answers - src/lib/bazaar.ts: bridge to the Android WebView wrapper; checkout uses Bazaar IAP only inside that app, Zarinpal everywhere else (unchanged) - android/: WebView wrapper with Poolakey; written but never built Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
