Overview

Per-element render context. Holds the immutable inputs each compartment renderer needs (bounds, classifier, fill/stroke, font, geometry, line data). Built once per element; passed to every compartment in the pipeline so they don't reach back into the parent Elements orchestrator.

Value object: equality by structural attributes. Each instance is frozen after construction.
