 * The legacy `AmplifyClass`-shaped surface exposed on
 * {@link LegacyAmplifyServerContext.amplify}.
 *
 * It is a *reverse bridge*: a full, **branded** {@link AmplifyContext}
 * (delegating to the real per-request context) that additionally exposes the
 * `AmplifyClass` members old published consumers — notably
 * `@aws-amplify/adapter-nextjs` ≤ 1.7.3 and the code it hands the instance to —
 * touch at runtime:
 *
 * - `getConfig()` → the context's frozen `resourcesConfig`
 * - `libraryOptions` → the context's `libraryOptions`
 * - `Auth.fetchAuthSession` / `Auth.clearCredentials` / `Auth.getTokens` →
 *   delegate to the context's auth closures
 *
 * Because it is branded, new context-first internals (e.g.
 * `generateClientWithAmplifyInstance` in `@aws-amplify/api-graphql`, which the
 * old adapter passes this object to) accept it as a regular
 * {@link AmplifyContext} without re-bridging.
 *
 * Members of the old `AmplifyClass` that cannot be meaningfully supported in
 * the singleton-free model (`configure`) throw a descriptive
 * {@link AmplifyServerContextError} instead of failing with an opaque
 * `TypeError`.
 *
 * @deprecated Exists solely so OLD published `@aws-amplify/adapter-nextjs`
 * versions (≤ 1.7.3) keep working against this version of `aws-amplify`. It
 * will be removed in the next major version.
