 * The page is built as a working paper: a cool printout ground, ink text,
 * every number and identifier set in a monospace utility face like a schedule,
 * and EY yellow used in exactly one role — a highlighter mark on the release
 * that is current. Nothing else is yellow, so the colour keeps its meaning.
 *
 * Committed to a light theme on purpose: working paper is paper.
