Commit A delivers an integrated, event-sourced Reddit import path (EntityImported + full payload storage/replay, explicit UI fetch control, configurable API bases, force-bypass cache, fixtures + end-to-end mock test) that replaces auto-fetch on browse and wires into the reducer/state/HTML layers. Commit B only drops an unintegrated standalone reddit.rs client with rate-limiter wrappers and Serde types, adding no wiring, persistence, or UI value to the project.
