The Clean theme is intended to be cloned. As you note, it inherits almost all of its content from another theme (Bootstrapbase) and most changes by core developers would be made to that parent theme and so get picked up by any Clean-clone themes.

In general child themes are the way to go, but since there's actually a fair amount of stuff you need to do to get a minimum viable Moodle theme Clean was created to give a better starting point than an empty directory.

I think some people think that Clean itself has grown too complex for this task, so another Cloneable theme called "Easy" was started:

Just to be boring, I was going to say that with so many free fonts available, one that isn't openly licensed isn't really worth bothering with, but it seems they've received feedback on that already and made it public domain. Or at least, "this free version of Comic Neue" is public domain. I wouldn't be surprised if the upcoming version that supports European characters wasn't, as charging for it later seems to have been part of the plan all along.

There's 114 "handwriting" fonts on Google fonts, all under proper open font licences.

Relatedly, there's a programming font that used to be called Cosmic Sans Neue Mono:

Try:

#middle-blocks .span4:nth-child(2) > div {background-color: red;}

You've currently got a div with a white background which is hiding the red. You probably want to change its styles (you might have to change the border colors too, depending on what you want to achieve).

Favicon images are notoriously hard to clear from caches. Try accessing the site from a computer/browser which you've never used to access it before (or visit the favicon URL directly and hit ctrl-F5 to force refresh ). If you see the new favicon then you've done it correctly, but it might take a while for various caches to update.

I can recreate it on Linux, with a "test.name.css" file that doesn't work but changing it (in config.php and the filename) to testxname.css works.

There seems to be a wider problem where it isn't always giving the correct response to files it doesn't find rather than 404 it's just returning a blank file.
