~x-ai/grok-latest → A (2:1)

A fixes real crashes in the OAuth/Reddit HttpServer mocks (string vs regex split, getRequestBody, nil-safe tokens/state, 302 body length, handler try/catch) that had broken Playwright auth E2E, plus selector/wait hardening—directly restoring critical test infrastructure. B is solid product work (chromeless fullscreen layout, left-oriented edge sorting, preview morph, CSS/docs/tests) but is enhancement of one UI flow rather than unblocking core auth verification.
