* Add zoom-aware symbology, fix globe popovers, expand geo coverage Map rendering improvements based on user feedback: - Globe markers now scale with camera altitude (onZoom hook) - Priority-based visibility culls low-priority markers at world view - Globe popovers use getScreenCoords for accurate positioning - Flat map labels hidden at low zoom, revealed progressively - Default globe altitude lowered from 2.5 to 1.8 for better fill - Americas region zoom tightened to CONUS focus Geographic coverage expansion: - 4 new OpenSky air theaters: Caribbean, Gulf of Guinea, Cape Route, Horn of Africa - Flight corridors now span Americas and Africa - NOAA alerts extract centroid lat/lon from GeoJSON geometry - EPA RadNet stations geocoded with hardcoded coords for 10 US cities - ISS + Tiangong positions estimated from TLE orbital elements - GDELT geoEvents() now called in briefing for mapped event points - New legend entries: Weather Alert, EPA RadNet, Space Station, GDELT Event * Fix null-safe coordinate checks and remove injected data blob - Use `!= null` instead of truthy checks for lat/lon in noaa.mjs and inject.mjs so valid 0-coordinates (equator/prime meridian) are not silently dropped - Reset jarvis.html `let D` back to null placeholder so generated runtime data is not part of the PR diff * Remove re-injected data blob from jarvis.html Reset let D back to null — previous commit was correct but inject.mjs build verification re-injected the payload.
