For some reason, I don't know what, I had the sudden urge to remove the uppercase transform from the headings on the site. A random spur of the moment decision.
That meant I also had to make some adjustments to kerning because the value I was using now looked awful.
Headings here have been ALL CAPS since the big re-launch in March 2016 so I'm not sure why my brain chose now, over 7 years later, to decide it was time to change.
