@vincentsarago, I've uploaded a sample VRT now, it's at https://syd1.digitaloceanspaces.com/mis-geotiff-storage/production/raster/nbgi_clipped_2024.vrt. Use &rescale=-0.3,0.3 to scale to visible values. Feel free to test things and lemme know if any changes are needed.
Cc @lillythomas who will be uploading the VRTs for the other years.

small titiler hack, we use a special notation for the endpoint prefix /dataset/{dataset_id}/years/{year}. This will tell FastAPI to look for Path parameters (define in our custom DatasetPathParams)
