/*
 * Kalon Theme — header (nav) styles
 *
 * Extracted verbatim from mu-plugins/kalon-nav.php on 2026-04-09 as part of
 * the Phase 1 theme refactor. The PHP file now only emits the <nav> markup +
 * its inline scroll/hamburger script; this stylesheet is enqueued globally
 * by kalon-theme/functions.php so FlyingPress can combine + critical-CSS it.
 *
 * If you change selectors, keep them in sync with the markup in kalon-nav.php.
