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

Side A fixes a real correctness issue (wire URLs for ontology items/votes/threads were wrong for private rooms across many RPC endpoints) and replaces a client-only, flicker-prone theme switcher with a server-rendered cookie-based theme that persists correctly across auth/redirects, backed by new unit tests. Side B is a well-scoped but narrower feature (pool-scoped voting) that adds genuine value but touches far fewer correctness-critical paths and has smaller overall impact on the project's URL/API consistency.
