/*
 * ── Z-INDEX STACKING ORDER ──────────────────────────────────────────
 *
 *  -1   Background decorations (hero gradients, bg shapes)
 *   1   Inline hover lifts (heatmap cells, calendar days)
 *   2   Chart overlays, demo overlays
 *  10   Tooltips, sticky sub-headers, floating elements
 *  50   Back-to-top button
 * 100   Navbar (default)
 * 101   Navbar dropdown menus
 * 150   Settings sidebar (mobile)
 * 175   Settings sidebar overlay (mobile)
 * 200   Settings tab bar (sticky)
 * 800   Map overlays (outage-map legend)
 * 900   Map panels (outage-map side panel, mobile drawer)
 * 999   Map floating search
 * 1000  Modals & overlays (brand, cert, dashboard, settings, alerts)
 * 1100  Nested modals (cert detail modal, map mobile filters)
 * 2000  Toast notifications
 * 9999  Temporary progress overlays
 * 10000 Skip-to-content link (accessibility, topmost)
 *
 * Rules:
 *  - Page-local z-index (1–10) can be used freely within components
 *  - Global overlays must use 1000+
 *  - Toasts must float above modals (2000)
 *  - Never exceed 10000 (reserved for skip link)
