GOOGLE_TAGMANAGER_CLIENT_ID — Google OAuth client id (refresh-token flow).
GOOGLE_TAGMANAGER_CLIENT_SECRET secret — Google OAuth client secret (refresh-token flow). Treat it as a secret.
GOOGLE_TAGMANAGER_REFRESH_TOKEN secret — Google OAuth refresh token; exchanged for access tokens automatically. Treat it as a secret.
GOOGLE_TAGMANAGER_ACCESS_TOKEN secret — Ready-made OAuth access token (~1h lifetime). Alternative to the client-id/secret/refresh-token trio.
GOOGLE_TAGMANAGER_OAUTH_PORT — Fixed port for the loopback listener of the in-chat login (127.0.0.1 + PKCE). Set it when the client runs over SSH port forwarding; otherwise a free port is picked per login.
GOOGLE_TAGMANAGER_API_BASE — API root host override.
GOOGLE_TAGMANAGER_TIMEOUT_MS — Per-request timeout in milliseconds.
GOOGLE_TAGMANAGER_MAX_RETRIES — Retries on transient errors (429, quota 403, and 5xx/network for reads).
GOOGLE_TAGMANAGER_MIN_INTERVAL_MS — Minimum spacing between API requests, for the 0.25 QPS quota.
