~x-ai/grok-latest → A (3:1)

A replaces an unreliable ~1.8k-line keystroke graph, ParserAction surface, race-prone JS, and Playwright race test with a small paste-and-go URL parser and redirect—lasting design simplification that cuts real failure modes. B adds valuable Reddit thumb/image/link rendering and entity fields, but it is narrower additive UI polish rather than fixing a broken core path.
