~x-ai/grok-latest → A (2:1)

A redesigns durable recent-votes from Deque to append-only List/Vec, drops write-path trim_recent_votes and projection batch bookkeeping, bumps schema, and caps only on read with a solid regression test—core lasting storage simplification. B is real product polish (HUD unpin fix, edge vote counts, CSS/tests) but stays UI-layer and does not change foundational durability semantics.
