Side A performs a substantive architectural consolidation: it removes the redundant web_post.rs endpoints (/post, /post/check, /post/redact), unifies all browser mutations behind the single POST /ui + __rpc__ dispatch, introduces a session-resolution helper (WebSession/resolve_web_session) to avoid duplicate header/cookie parsing, and updates templates, JS, tests, and fixtures to match—an end-to-end simplification of the routing surface. Side B is a much smaller, localized cleanup that trims unused parameters/logic from vote_compare_post_success_js and removes a dead card-render call, which is useful but minor in comparison.
