// Fixture-derived root viewport overrides for Mermaid@11.15.0 EventModeling diagrams.
//
// These values are taken from upstream SVG baselines under
// `fixtures/upstream-svgs/eventmodeling/*.svg` and are keyed by `diagram_id` (fixture stem).
//
// EventModeling layout still uses deterministic headless text metrics, while upstream root
// viewports are browser `getBBox()` products. These pins keep the root-only parity gate stable
// after layout geometry has been brought into close alignment.
