The HIG states: "When the visual design calls for an area of exceptional focus, a larger typeface size may be used. In this case use a Light typeface weight to keep the stroke width similar to other styles throughout the interface" I think, if you want to have something like F6531451: Screenshot_20190107_145258.png <https://phabricator.kde.org/F6531451> you should use your own special sized label. And if you want to add so much focus on a text, it can be unique in its font size. To me it seams the predefined Header[1-4] are mainly to be used for regular content and chrome?
