~anthropic/claude-sonnet-latest → B (65:35)

B delivers a substantial, coherent feature (server-rendered theme cookie/select replacing JS localStorage switcher, applied consistently across every page handler) plus real room-aware URL fixes (item_path_for_api_in_room, forum_thread_web_url) with new tests, all preserving working functionality. A mostly rips out a working demo-counter feature (net code reduction, arguably a regression in test coverage) and adds a settlement/batching worker for votes that, while a reasonable design, is unproven and less broadly impactful than B's cross-cutting fix.
