I should probably add text-transform: uppercase as well to match the look if the specific font doesn't do it automatically, but the user only asked to change typography. However, "Distro" fonts are often all-caps. I'll stick to just font-family for now unless I see they need casing changes. Wait, looking at the images, they are indeed ALL CAPS in the design.
