/* ═══ Z-INDEX DOCTRINE (Jul 22 2026) ═══════════════════════════
   App chrome OWNS the top band: header + its dropdown ride at
   2000+ so the menu is ALWAYS reachable over workspace tools.
   Workspace floating UI (classbar, palette, popovers, mini menus,
   cascades) lives in 600–999. Modal overlays keep 9000 — a modal
   deliberately blocks everything, menu included. */
