/**
 * Battery-scoped exception constructors for Gemini media generation adapter failures.
 *
 * @module @nhtio/adk/batteries/generation/gemini/exceptions
 *
 * @remarks
 * Battery-scoped exception classes for the Gemini media generation adapter. These exceptions are
 * owned by the battery (not the ADK core) and are minted via `createException` from
 * `@nhtio/adk/factories`. Re-exported from the battery's barrel.
 *
 * The categories mirror the OpenAI Generation battery one-to-one so batteries across engines fail
 * with parallel semantics — only the engine-specific transport exception differs.
