~x-ai/grok-latest → B (2:1)

B permanently consolidates browser ingest/check/redact onto a single POST /ui path (WebSession, dispatch_ui_action), deletes the whole web_post module and /post* routes, and rewires forms/tests to __rpc__—lasting architectural simplification. A improves one page (chromeless fullscreen layout, edge-history sort/ratio orientation, preview morph) with real UX value, but its impact stays localized versus B’s system-wide cleanup.
