/**
 * Antigravity OAuth configuration constants.
 * Values sourced from cliproxyapi/sdk/auth/antigravity.go
 *
 * ## Logging Policy
 *
 * All console logging in antigravity modules follows a consistent policy:
 *
 * - **Debug logs**: Guard with `if (process.env.ANTIGRAVITY_DEBUG === "1")`
 *   - Includes: info messages, warnings, non-fatal errors
 *   - Enable debugging: `ANTIGRAVITY_DEBUG=1 opencode`
 *
 * - **Fatal errors**: None currently. All errors are handled by returning
 *   appropriate error responses to OpenCode's auth system.
 *
 * This policy ensures production silence while enabling verbose debugging
 * when needed for troubleshooting OAuth flows.
