/*
 * layout.css — site header, footer, archive listing and pagination.
 *
 * Frontend only; never loaded into the editor, which renders blocks and no site
 * chrome. (.container lives in base.css because block templates use it.)
 *
 * Ported from design/cookmushroom-design.html. Two deliberate departures:
 *
 *   1. The design's footer newsletter form is NOT ported. A newsletter needs an
 *      ESP, double opt-in and privacy-policy coverage; an inert form on a live
 *      site is worse than none.
 *   2. The design toggles `.site-header--open`. We keep our existing `is-open`
 *      class on `.site-nav`, which site.js already sets in the same function as
 *      aria-expanded, so the two cannot disagree. No sibling combinator (rule 2).
 *
 * Header CTA: add CSS class `is-cta` on a primary-menu item (WP menu UI).
 *
 * Rule 9 applies; this file defines no tokens, so it holds no colour, font-size
 * or spacing literals.
