openai/gpt-chat-latest → B (2:3)

Side B adds a cohesive feature with lasting architectural value: it extends `EntityData` with `image_url` and `link_url`, introduces a dedicated `render::reddit` module, updates HTML rendering to display Reddit-specific cards and thumbnails, and adds a regression test covering preview/image extraction. Side A adds useful infrastructure (Dockerfile, Fly config) and new persistence helpers (`EventLog`, `ViewStore`), but much of it is deployment scaffolding or isolated utilities without showing equivalent integration into the application's behavior.
