~x-ai/grok-latest → B (2:3)

B redesigns core vote projection storage (Deque→List/Vec, write-time trim removed, query-time cap, schema v4) with a focused unit test, which is a lasting data-model change in the hot path. A’s valuable fixes (out-of-band WEB_BROWSER_AGENT delegation, no all-items fallback when sibling pool < 2) are real, but much of the diff is route rename (/vote/compare→/vote), nav cleanup, and test URL churn.
