/* ============================================================
   NextGen MIS — Coverage map (.ng-coverage-map)
   ------------------------------------------------------------
   The Leaflet choropleth on the Programme Indicators dashboard.
   Loads after _cards.css (it lives inside .dashboard-chart-card)
   and after leaflet.css (pushed to @stack('styles'), which the
   refinements bundle follows), so every rule here wins on equal
   specificity without !important — except where Leaflet sets its
   own, annotated inline.

   Fill colours are read by coverage-map.js from the --map-* tokens
   (_tokens.css) at draw time and again on ng-theme-change, because
   an SVG path's fill is set per feature in JS. Everything that is
   plain chrome — legend, level switch, attribution, tooltip — is
   styled here and flips with the theme on its own.
