Overview

Per-render mutable state holding the components encountered during ERB evaluation. One instance is allocated by the controller per render, passed explicitly through the pipeline, and discarded when the response is sent.

No shared state, no thread-local lookup — the instance lives only as long as the render call. Satisfies NFR8 and the ‘Ruact/NoSharedState` cop with zero exceptions in `lib/`.

Internal API: not part of the public compatibility contract.
