B introduces a genuine algorithmic improvement (bridge-preferring pair selection in pair.rs) and fixes a real correctness bug where Reddit permalinks with title slugs created duplicate ItemIds (ItemId::from_storage), backed by new unit and integration tests plus a Clojure e2e test. A is a solid but more mechanical feature (server-persisted theme cookie threaded through ~20 handlers) plus useful but secondary private-room URL prefixing fixes; it's broader in diff size but less deep in core logic than B's ranking/pair-selection and id-normalization fixes.

council reasoning
B adds lasting core product logic: bridge-first pair selection in pair.rs (with unit tests), a full /vote compare UI with post-vote edge-history morphing, and ItemId::from_storage normalization plus integration coverage. A mostly plumbs cookie-based theme through layout/handlers and secondary private-room wire URL helpers in RPC—useful polish and API consistency, but less foundational than the ranking/vote path work.
Side A delivers two substantial, project-wide improvements: persistent theme support via cookies integrated across authentication and HTML rendering (including preserving the theme through login redirects), and correct room-aware URL generation throughout the RPC/API layer with dedicated helper functions and tests. Side B adds a useful vote-comparison UI flow with in-place morph updates and improves item normalization for Reddit imports, but much of the patch is feature-specific, whereas Side A fixes cross-cutting behavior affecting navigation, rendering, and API correctness across the application.
