Side A shows a genuine architectural improvement: it removes the ad-hoc, hardcoded per-domain combinator engine (engine.rs, with special-cased reddit/youtube logic) in favor of a documented generic graph/DFA approach with a fallback for unknown sites, generalizing URL canonicalization beyond two hardcoded domains. Side B bundles plumbing (new deps, typed form holes, a vote CTA link, CSS/JS for a slider) but its core new logic (vote.rs, pair.rs) isn't visible in the diff, making it hard to verify the actual 'fix' beyond UI wiring and dependency additions.
