Testing PMTiles Overzoom Feature
=================================

1. Testing function existence:
   tileid_to_zoom exists: YES
   compute_zoom_range_from_entries exists: YES

2. Testing tileid_to_zoom():
   TileID 0 => zoom 0
   TileID 1 => zoom 1
   TileID 2 => zoom 1
   TileID 5 => zoom 2
   TileID 99 => zoom 4
   TileID 213 => zoom 4
   TileID 10377 => zoom 7

3. Testing with cached data:
   Root cached: 2578 bytes
   Parsed entries: 102
   Computed zoom range: 0 - 17

4. Testing overzoom logic:
   Original request: z=10, x=232, y=148

Test complete!
