#   fly volumes create temetro_data --size 1    # persists auto-generated secrets + uploads
#   fly postgres create                          # then:
#   fly postgres attach <postgres-app-name>      # sets DATABASE_URL secret
#   fly secrets set \
#     PUBLIC_RELAY_URL=https://<app>.fly.dev \   # baked into the wallet-import QR (must be public https)
#     BETTER_AUTH_URL=https://<app>.fly.dev \    # https → secure auth cookies
#     FRONTEND_URL=https://<your-frontend-origin>
#   fly deploy

# Any other Docker host (Render/Railway/VPS) works with the same env contract;
# Fly is just the concrete example.
