   MASTHEAD — sticky positioning

/*
 * STACKING CONTEXT STRATEGY
 * ─────────────────────────
 * Problem: giving #masthead a z-index while it has `position: sticky`
 * creates a new stacking context. Any z-index set on children (e.g.
 * sub-menus at z-index:99999) is then relative to that context, not
 * the document root — so dropdowns that visually escape the header
 * can still be clipped by later stacking contexts (hero, page content).
 *
 * Fix: #masthead is sticky so it stays on top naturally. We give it
 * a high z-index ONLY to beat the hero/content layers below it.
 * The desktop-header wrapper must NOT create its own stacking context
 * (no transform, no filter, no isolation) so that sub-menu z-indexes
 * are resolved against the document root where they can beat everything.
 *
 * Sub-menus use `position: absolute; z-index: 99999` (from
 * style_e5887fb628b6.css) and are therefore above all page content.
