/* Hitbox is the apex circle plus the wedge polygon fills; gaps between

   so clicks there fall through to the map. The apex and wedges each
   re-enable pointer events for themselves and bubble their events up
   to the marker container, where Leaflet dispatches them. Three classes
   are required to out-specific Leaflet's own
   `.leaflet-marker-icon.leaflet-interactive { pointer-events: auto }`
   rule — equal specificity isn't enough because Vite injects Leaflet's
   bundled CSS after our static `styles.css` link, so the later rule wins
   on ties. Adding `.leaflet-interactive` (which Leaflet adds to every
