Side A implements a substantive architectural change: it vendors a RocksDB-backed durable crate, moves large Reddit JSON payloads out of the in-memory GlobalTree into an EntityStore, and switches event-log loading from load-all-into-memory to a streaming line-by-line replay, with accompanying tests and integration updates across reddit.rs, reducer.rs, state.rs, and event_log.rs. Side B is a small cosmetic 'nits' commit that removes two UI elements and flips CSS gradient directions on vote sliders, with no functional or architectural impact.
