# Fly.io deployment. `fly deploy` builds the Dockerfile and ships the binary.

# v1 is single-instance: all room state lives in process memory, so DO NOT scale
# past one machine (no cross-instance state sharing). Keep `fly scale count 1`.
# Set BASE_URL so the room links returned at creation point at your real host:
#   fly secrets set BASE_URL=https://<your-app>.fly.dev
