blockly injects its styles into the <head> element.  When these styles were up there, they were before blockly's.  Then we could not override things like font-face.  Whereas on our main page, the common.css is linked to from the footer of the dashboard page (!), which allows us to overrides blockly's styles.  So I moved here to be more like the main page.  But it still doesn't work because of our font DRM.
