~x-ai/grok-latest → A (3:1)

A fixes a production-breaking Reddit fetch path (no public www fallback from cloud IPs, OAuth required when creds exist, 401/403 refresh/retry, clearer AuthRejected handling) plus a deploy pin for SORTER2_BASE_URL—core reliability. B is a polished UX add-on (CopyGardenRank markdown clipboard, wire-up, tests) that reuses existing patterns but does not fix foundational breakage.
