    Class PopulationOverlay

    A hex choropleth over the terrain: one prism (or flat tile) per H3 cell, coloured by density, land use, night lights or habitability, plus the road / rail / power network as lines. With resolution: 'auto' it switches to coarser, parent cells (exact sums of their children) as the camera pulls away.

    const overlay = new PopulationOverlay({ population, camera, mode: 'density', extrude: 600 })
    scene.add(overlay.object)
    renderer.setAnimationLoop(() => { overlay.update(); renderer.render(scene, camera) })
