 * the settings UI can decide whether to offer the "Connect Builder.io"
 * path. With the flag set to `"false"` the generation pipeline refuses
 * Builder-managed runs (see `generateWithManagedImageProvider` in
 * `generation.ts:217`), so the settings page would otherwise lead users
 * down a setup path that can't succeed.
 *
 * Kept advisory — generation actions still check the flag themselves.
