Side A adds a substantial Reddit-specific rendering layer: it extends `EntityData` with `image_url`/`link_url`, extracts those fields during Reddit parsing, introduces reusable `render::reddit` components for entity pages and ranking rows, integrates them into existing HTML, and adds parsing tests plus a fixture. Side B mainly prepares infrastructure for a voting flow (typed form holes, redirect support, route wiring, CSS/JS, dependencies), but the core voting implementation is absent from the patch, making its lasting functional value much smaller than A's completed feature.
