"""titiler app for the 1 m CHM, with the STAC + MosaicJSON docs served locally.

titiler's document fetchers (rio-tiler STACReader, cogeo-mosaic web backend) use
httpx, which does NOT follow HTTP redirects by default. Hugging Face's
`resolve/main` URLs 307-redirect to a CDN, so fetching a STAC item or MosaicJSON
straight from the dataset repo fails (the COGs themselves are fine — GDAL follows
redirects). We therefore mount the catalog + mosaic as same-origin static files
under `/data`, and point the `?url=` params at this Space's own origin.
