Heritage analyst here. I've put together `heritage_sites.geojson` from my own field work, and every site in it is several features sharing a `site_id`. I need to load the data into our desktop tool, which only ingests typed GPKG layers, no mixed-geometry files, and every feature has to be single-part. Can you give me back `heritage.gpkg` with three layers named `points`, `lines`, and `polygons`, keeping the `site_id` on every feature so I don't lose the cross-layer link? Use Egypt's national grid.

Let me start by reading the `heritage_sites.geojson` file to understand its structure and geometry types.

Let me analyze the data:

1. I have a GeoJSON file with mixed geometry types: Point, LineString, Polygon, MultiPolygon
2. I need to create a GPKG with three layers: `points`, `lines`, `polygons`
3. Each feature should be single-part (so MultiPolygon → Polygon)
4. Every feature needs to retain `site_id`
5. Use Egypt's national grid (EPSG:32635 - UTM zone 35N, or possibly EPSG:22992 - Egypt Red Belt / EPSG:22993? Let me think... Egypt's national grid is usually EPSG:32635 (UTM zone 35N) which covers most of Egypt. Actually, there's also the "Egyptian National Grid" which is EPSG:22992 (Egypt Red Belt). Let me check.

Actually, "Egypt's national grid" most commonly refers to the "Egyptian Transverse Mercator" - EPSG:32635 (WGS 84 / UTM zone 35N) which covers Cairo. But there's also the older "Egypt Red Belt" (EPSG:22992). Let me use EPSG:32635 as it's the most standard modern one for Cairo area. Actually, I'll use EPSG:32635 - WGS 84 / UTM zone 35N which is appropriate for Cairo.

Let me write a Python script to:
1. Read the GeoJSON
2. Separate features by geometry type (Point, LineString, Polygon)
3. Explode MultiPolygon into individual Polygon features (and if there were MultiLineStrings, explode them too)
4. Reproject to EPSG:32635
5. Write each layer to the GPKG

Let me write the script.

Actually, let me check what CRS Egypt's national grid is. The most common ones:
- EPSG:32635 - WGS 84 / UTM zone 35N (covers Cairo at ~30°N, 31°E)
- EPSG:32636 - WGS 84 / UTM zone 36N
- Old Egyptian system: EPSG:22992 (Egypt Red Belt)

Since Cairo is around longitude 31°E, which is in UTM zone 35N (30°E to 36°E), EPSG:32635 is the right UTM zone. Let me use that.

Let me write the Python script.
