  /* ── z-index scale ──────────────────────────────────────────────
     Single source of truth for stacking. Leaflet's own ceiling is its
     control container at z-index 1000; EVERY overlay layer below is set
     ABOVE 1000 so it wins even if the map's stacking context is ever
     broken by a plugin. The map wrapper is also isolated (see
     .leaflet-container) as a second line of defence.
