Docker-based sync backend for the Anki app (afrima/anki-sync-server, the
official Rust sync server). Supports multiple independent accounts per
instance, the repo's multi-instance pattern, port collision avoidance,
Caddy wiring, and update/fresh/cancel reinstall detection.
No Authelia gate — this is a raw sync API the Anki client talks to, not
a browser session, so a forward_auth portal in front of it would just
break every sync request; SYNC_USER1/SYNC_USER2/... is its own auth
boundary.
Companion services/anki-sync-server.md covers client setup (Desktop,
AnkiDroid, AnkiMobile) and the Quizlet import/export walkthrough.
