@Gargron one suggestion: make the font a bit smaller so more words get in. (This screenshot is from Safari on iOS. I am zoomed in to 125% because I have old eyes, but I’m sure I’m not the only one who does that.) I’ve designed many systems like this and I know the temptation to make a big headline font, but people will understand it’s a headline because of the rest of the design even if the font size is only a little bit larger than the body size.
