/* LinkAIG site chrome: header, mobile menu, footer and client-login modal.
 *
 * Shared by every page. The v3 homepages link it next to css/v3.css; inner
 * pages get it injected by js/layout.js. Inner pages also carry Bootstrap 5
 * and the legacy stylesheets, so everything here is scoped under the lx-
 * roots, tokens included (inner pages define their own :root variables), and
 * resets the Bootstrap/legacy defaults it would otherwise inherit:
 *   - styles.css sets `*:not(html):not(body) { max-width: 100% }` and
 *     `header, footer, nav { overflow-x: clip }`, which would squash and clip
 *     the dropdown;
 *   - Bootstrap reboot adds margins/padding to p, ul, h4 and colours links.
