Side B introduces a real architectural improvement (offloading Reddit JSON payloads to RocksDB via a new durable crate, streaming event-log replay, and updated tests/integration) that reduces startup RAM and improves persistence design, despite heavy vendored lockfile noise. Side A is a legitimate but much smaller bugfix/UI polish for vote-compare highlighting and slider gradient logic, valuable but far less impactful than B's structural storage change.
