/**
 * Shared header stack: utility bar + nav.
 * Used by index.html, panhandle-region.html, and other region pages.
 * Requires :root { --navy, --gold, --coral, --white } to be defined on the page.
 *
 * Canonical values (change here only; keeps all pages in sync):
 * - Utility bar height: 40px
 * - Nav height: 64px
 * - scroll-padding-top: 104px (40 + 64) — both bars live inside one sticky wrapper.
 *
 * Sticky behavior: The entire header (utility bar + nav) is wrapped in
 * .header-sticky-wrapper, which is position: sticky. Both bars stay visible
 * at the top, so anchor links always offset by 104px. No 64 vs 104 trade-off.
