What are the size limits on the bgremove transformation?

I’m trying to figure out what the max resolution and filesize is for the e-bgremove (?tr=e-bgremove) transformation but it’s not documented.

As test, an image of 18.8MB and a resolution of 3648x5472px (less then 20MP)

We only see the following error in the headers:
ELIMIT - The size of the input image to e-bgremove is too high. Reducing quality or resolution can help bring the size down. You can retry the request in 5 minutes.

The e-bgremove transformation can process images up to 10 MB in file size. The maximum supported Resolution is determined by your plan limits and is currently set to 100 MP. Any image that exceeds either the image size or resolution limit will result in an ELIMIT error.
