Whether NASA publishes a DMR++ sidecar for short_name’s granules.

The sidecar is what makes earthaccess.virtualize() cheap; without it every granule’s metadata has to be parsed. CMR lists the sidecar in the granule’s RelatedUrls, so this is a metadata query — no login, no download, and no ambiguity from an Earthdata Login redirect (an unauthenticated request for the sidecar itself answers 302 to a login page whether or not the file exists).
