/*
 * Site chrome — the header bar's layout, the skip link, the current-page and
 * focus states for the nav links and the mini cart, and the footer columns.
 *
 * Builds on the header and mini-cart rules in assets/css/cart.css rather than
 * redeclaring them: this file adds the bar's flex row (so the menu and the cart
 * pill sit on one line inside the nav), the keyboard states, and the
 * current-page treatment. Every value comes from assets/css/design-tokens.css,
 * so a [data-theme="dark"] remap of the role tokens recolours the whole bar.
 *
 * Mobile-first: the bar is a wrapping row that works with no JavaScript at all.
 * assets/js/nav-toggle.js then adds .hcr-nav-js, which turns that row into a
 * disclosure below 48em — the SAME single menu, collapsed behind a labelled
 * button, never a second copy of it in the DOM. Above 48em the button is gone
 * and the row is back, so the inline nav and a drawer are never both visible.
