/*
 * specimen.css — the page's own CSS, and nothing else's.
 *
 * This file exists to be honest about a thing every design system elides: the
 * documentation page always needs more than the system provides. Rather than
 * quietly growing chapbook.css until it covers tables, tab groups and
 * swatches that no real site needs, the extras live here, scoped to this page.
 *
 * That is also the recommended pattern for using the system. Take
 * chapbook.css unchanged, add a file like this one beside it, and keep the
 * two separate so you can always see what you added.
 *
 * Everything below obeys the nine rules. No radius, no shadow, no fill except
 * --sunk; hairlines and space do the separating; mono carries structure.
