# Shareable stack: ThreeHats rest-api relay + browser-served Obsidian.
#
# Brings up the two containers the sync tool needs alongside an EXTERNAL Foundry
# instance (you supply FOUNDRY_URL — Foundry itself is not bundled; it needs a
# license + the rest-api module installed). The sync tool itself stays host-run
# (./sync.sh ui) so it can read the journal LevelDB and shell out to `docker`.
#
# Copy .env.example -> .env and fill it in, or run the /setup skill which does it
# for you. Then:  docker compose up -d
#
# NOTE on networking: Foundry's rest-api module connects OUT to the relay over
# WebSocket. If your Foundry is on a different host than this compose, the relay's
# port (RELAY_PORT) must be reachable from Foundry (port-forward / tailnet / public
# domain). RELAY_URL below is what the *tool* calls (usually localhost).
