/* LAKANA CANONICAL HEADER — Tier-1 reviewer-critical shell
 *
 * One namespaced stylesheet for the single canonical global header, so
 * Tier-1 pages stop depending on any of the six separate global-header
 * implementations Phase 0 found. Visual language (navy / teal / gold /
 * iris institutional palette) and the responsive-collapse behavior are the
 * already-approved design from assets/lakana-elite-menu.css, carried
 * forward under a strongly namespaced .lakana-canonical-header / .lch-*
 * selector set rather than redesigned. Tier-2 pages do not load this file
 * and are unaffected by it. */
