~anthropic/claude-sonnet-latest → B (3:1)

Commit B implements a substantial, working feature: a background Reddit fetch worker with OAuth token handling, rate-limit/backoff logic, URL mapping, JSON parsing, and integration into app state/routing, backed by unit tests. Commit A is a small, valuable but narrow security fix (HTML sanitization via ammonia) plus a large generated Cargo.lock diff, which is useful but much smaller in scope and lasting design impact than B's core feature implementation.
