// UTILITIES ▸ Import on Navara under the strict network policy: GeoJSON,
// KML, KMZ (a packed icon and a ground overlay) and GPX through the real
// file input, each one row; Navara draws their shapes in the row colour and
// their pins and packed ground overlay; unsupported content is counted
// in the hint; hide, fly-to and remove work on the engine; the files
// survive a switch to Cesium and back and draw on each engine. No file makes
// the page request anything it names (the strict policy fails any request
// outside the preview and the free tile cache).
