Usage and interface
BenchmarkSource keeps a source link and recorded date beside a chart or table. Supply generatedAt as an ISO date string and href as the source URL. The optional label defaults to “Committed snapshot”. The printed date uses UTC and retains the complete timestamp in a native time element.
<BenchmarkSource generatedAt="2026-07-01T00:00:00Z" href="https://rc.css.master.co/benchmarks#data-sources" label="Illustrative source date"/>Use a real source when presenting measurements. A source footer supports the surrounding methodology and limitations; keep those explanations in the document. The component does not fetch data or infer when a run occurred.
