<HazardLayer>

<HazardLayer
  type="river_flood"
  visible
  opacity={0.6}
  colorRamp={{ type: 'linear', stops: [...] }}
  missingColor="#888888"
  safeColor="#9ad48a"
/>

<FloodLayer> / <InlandFloodLayer> / <TsunamiLayer> / <StormSurgeLayer> / <LandslideLayer>

Thin aliases. <FloodLayer opacity={0.6} /> ≡ <HazardLayer type="river_flood" opacity={0.6} />.

<FootprintLayer>

PMTiles-driven extruded footprints. Auto-mounts from <FallbackExtrusionLayer> when needed.

<FootprintLayer
  zoom={15}
  pmtilesUrl="https://cdn/.../buildings.pmtiles"
  flat={false}
  colorBy={(attrs) => attrs.height && attrs.height > 50 ? '#f0a' : '#5ab'}
/>

<FallbackExtrusionLayer>

Mounts a <FootprintLayer> automatically when the runtime decides PMTiles fallback is needed.

<Plateau city="..." fallback="auto">
  <FallbackExtrusionLayer />
</Plateau>

<TileDebugLayer>

Wireframe boxes around each loaded tile, colored by lifecycle state. Use for debugging tile loading and feature_id detection.

<TileDebugLayer states={['featureIdMissing']} opacity={0.5} />
