Issue

Downloading packages on Anaconda Cloud via a web browser (Safari 16.6.1) leads to a file like (for example, from https://anaconda.org/conda-forge/r-tinytex/files):

noarch_r-tinytex-0.49-r43hc72bb7e_0.conda

This fails to unpack with cph

(cph) $ cph x noarch_r-tinytex-0.49-r43hc72bb7e_0.conda 
Traceback (most recent call last):

However, everything goes smoothly when downloading the file programmatically using the link on the Anaconda Cloud page:

(cph) $ wget https://anaconda.org/conda-forge/r-tinytex/0.49/download/noarch/r-tinytex-0.49-r43hc72bb7e_0.conda
(cph) $ cph x r-tinytex-0.49-r43hc72bb7e_0.conda

This behavior arose in the last few months. Is Anaconda Cloud doing something different when downloading from a web browser?
