feat: import GeoJSON, KML, KMZ and GPX files onto the globe
DISPLAY ▸ Import (and drop onto the globe) puts the person's own files on the map as Cesium data sources, clamped to the ground, one color per file, with a row to show/hide, fly to or remove each. Files stay in the browser for the session. KML/KMZ are sanitized before Cesium reads them (network links, remote icons/styles, models, photo/screen overlays and balloon HTML removed; KMZ images served from blob URLs), so an imported file cannot make the page fetch anything. KMZ is read with a small dependency-free zip reader on the platform DecompressionStream, with a zip-bomb limit. Bounded file size, entity count and number of files. Tests: src/data/geoFileImport.test.mjs, src/ui/geoFileImport.test.mjs. Gate: scripts/qa-geo-import.mjs. The import half of #890. Co-Authored-By: Claude Opus 5.5 <[email protected]>

/**

* DISPLAY ▸ Import: put your own GeoJSON, KML, KMZ or GPX files on the globe.
|
||||
*
|
||||
* Files come in through the Import button or by dropping them onto the globe.
|
||||
* Each one becomes its own Cesium data source, clamped to the ground, with a
|
||||
* row in the panel to show or hide it, fly to it, or remove it. Files are read
|
||||
* in the browser and never uploaded; see `src/data/geoFileImport.js` for what
|
||||
* is accepted and what is stripped from KML before Cesium reads it.
|
||||
*
|
||||
* Imported files last for the page session: a reload starts empty.
|
||||
* `destroy()` removes every imported data source, revokes every blob URL and
|
||||
* gives back every listener and the `window.__gevGeoImport` handle.
