### Is this a duplicate?

### Describe the incorrect/future/missing documentation

Hi, I noticed that today Thrust's doc pages, e.g. [this one](https://nvidia.github.io/cccl/thrust/api/groups/group__transformations.html), apparently were removed and now return 404 when found in Google (they are still indexed). So could you let me know if this was intentional, and if so, where is the new documentation source? Thank you!

### If this is a correction, please provide a link to the incorrect documentation. If this is a new documentation request, please link to where you have looked.
