server/ was a standalone Express webhook/health service (couples-connect-server, 17 files)
that duplicated the Firebase Cloud Functions — entitlement logic, FCM sends, an answer
listener, a webhook route — and was documented as "not client-facing… most teams will not
need it." It hadn't been touched since 2026-06-20 (pre-dating the whole v2 Functions
migration), had no deploy/CI wiring, and was a standing source of "which backend is real?"
confusion. Cloud Functions are the sole backend.
Removed the directory + all doc references so nothing dangles: README + Engineering Reference
Manual directory trees and the "Optional Express server" section; the iOS ARCHITECTURE_AUDIT
intro, its Section 8 (now a "removed" note), and the file-count table.
