~anthropic/claude-sonnet-latest → B (6:4)

B adds genuinely new, tested functionality (typed `$form:i32` template holes with round-trip tests, a post-vote redirect via `next`, and wiring for a new `/vote` route with supporting CSS/JS), which extends the project's real capability. A is a more narrow internal refactor (Deque→Vec for recent_votes) that removes write-time capping (`trim_recent_votes`) in favor of read-time capping, a plausible simplification but one that trades bounded storage growth for simplicity, with less clear net benefit despite the added test.
