KeyValue

A compact key→value metadata row in the OCSS spec-block idiom: a mono small-caps muted label paired with a mono (tabular) or text value. Ideal for ids, hashes, versions, and environment facts. Each pair is a role=group named by its label, so screen readers announce it as one unit. An optional copy button writes the value to the clipboard via navigator.clipboard, swapping its icon to a check on success and announcing it in a polite live region. prefers-reduced-motion safe.
