[BUG] Site logo break layout

Looks like the site's logo was recently changed from a one-line logo (text + name) to two lines, which breaks the layout:

If the logo stays like this (two lines), a CSS rule should make sure that it doesn't overflow the header's height.

Start by locating the site's header and logo styles, then reproduce the two-line logo layout shown in the issue. Done means the logo remains within the header without overflowing or breaking the surrounding layout.
