/**
 * Subscription-based image generation: the internal, self-contained channel.
 *
 * Login (PKCE loopback), token storage through the DSH Credentials service,
 * refresh and the wire calls all live in `./subscription/` — adapted from
 * @goodandready/dsh-subscriptions (MIT, (c) 2026 GooDAnDReaDY), trimmed to
 * the two image vendors this bundle ships. This file keeps the same
 * `{ data, mediaType }` contract as the API-key adapters so `saveGenerated`
 * and everything downstream is shared.
 *
 * Isolation invariants (project rules):
 * - OAuth blobs live under CODEX_OAUTH_1 / GROK_OAUTH_1 refs — never the
 *   API-key refs — and the API-key paths never consult subscription state.
 * - Login/logout changes nothing except one vendor's own blob.
