/**
 * Grovidex site chrome (child-theme owned, site-wide).
 *
 * Styles the Grovidex header, footer and mobile bottom navigation
 * rendered by the shared chrome partials (template-parts/chrome/):
 * on the static front page via the homepage templates, and on every
 * other route via the astra_header/astra_footer hook swap in
 * inc/chrome.php. No Astra Header Builder selectors are used or
 * required. The shared search-form skin (.gvx-search-form) lives in
 * header-footer.css so any Astra-rendered fallback search uses the
 * identical treatment.
 *
 * Breakpoint: 922px, matching the site's established header breakpoint
 * and the sticky-offset media queries in header-footer.css (which also
 * provide html scroll-padding-top and per-target scroll-margin-top
 * site-wide).
