I want to add a basic font, using common.css for English readers - unfortunately, @import has been disabled. There is clearly a perfectly rational reason for it to be disabled by default, turning it back on is probably obvious, in some clearly defined settings file. However, I just want to use a web-font, this seems to be the simplest way to do it.
Please educate me on the reason why it is turned off by default, and how to turn it back on.
