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

Side B is a genuine refactor that consolidates duplicated web_post.rs logic into ui_html.rs, removes now-dead /post routes, introduces a cleaner WebSession abstraction, and updates tests/fixtures accordingly—reducing code duplication and clarifying the dispatch path. Side A adds a real feature (vote page, typed form holes) but is messier: it bundles unrelated dependency additions (rand, urlencoding, zerocopy chain) into Cargo.lock, references an undefined vote module in the diff, and mixes CSS/JS additions with backend logic without clear architectural improvement.
