/*
 * How this site is built — /platform/.
 *
 * Two new shapes on this page: the stat pair in "The defect", and the record
 * inspector's two-column field list in "The record inspector". Everything
 * else borrows .bay/.shell/.eyebrow/.lede/.prose/.btn/.dentil from theme.css
 * rather than restyling it here.
 *
 * The inspector's two columns reuse the .practical/.also technique already
 * proven elsewhere in this theme: minmax(_, 1fr) on auto-fit, so the second
 * column drops below the first on a narrow screen with no media query and no
 * horizontal scroll.
 *
 * Colour note: the two columns are told apart by their top rule (--blue for
 * WordPress, --accent for Tessitura) and nothing else. An earlier draft tinted
 * the Tessitura column with --paper-raised; --ember as a link colour measures
 * 4.93:1 there, which clears AA but leaves little margin, and this build has
 * already been caught twice by axe on exactly this trap. Both columns stay on
 * plain --paper so every inline link keeps --ember's full 5.35:1.
