Side A delivers lasting functional improvements across the application: it implements persistent server-backed theme selection (including cookie handling across authentication redirects), propagates theme state through page rendering, and fixes private-room URL generation by introducing room-aware item/thread URL helpers used throughout the RPC API with dedicated tests. Side B makes a substantial parser redesign by changing the DSL to require block-first vote explanations and updates documentation and tests accordingly, but much of the patch is migration churn for the new syntax rather than new end-user capability.
