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

Side A adds a genuinely new, well-tested ranking algorithm (pair.rs's bridge-aware next-pair selection with component detection) plus a real bugfix in ItemId normalization (from_storage) that fixes vote/id mismatches from Reddit title slugs, along with an in-place morph-based vote-compare UI backed by integration tests. Side B's changes (explicit fetch button, raw-payload event storage, dotenv, configurable Reddit API base) are solid plumbing/UX improvements but are more incremental infrastructure rather than a core algorithmic/product feature.
