// Fixture-derived root viewport overrides for Mermaid@11.12.2 Timeline diagrams.
//
// These values are taken from upstream SVG baselines under
// `fixtures/upstream-svgs/timeline/*.svg` and are keyed by `diagram_id` (fixture stem).
//
// They are used to keep `parity-root` stable at higher decimal precision when browser float
// behavior (DOM `getBBox()` + serialization) differs from our deterministic headless pipeline.
