After a few days of tweaking the templates used by the software that
generates the Phys-L archives, I have regenerated the official archive
pages. The end result is the archive pages are much more readable on
mobile-devices.
I've done a few spot checks with various browsers on both mobile and
desktop devices and things look good on my end. If you find something looks
funny when viewing the archives on your end, I would like to hear about it.
