A request: could you please remove "case" from the font-feature-settings on the root element of https://www.dflex.dev/. It’s wrong (its purpose is to tweak vertical positioning of punctuation to align with all-caps text, which is not the case here), and some fonts (including a couple of the largest font foundries) also have "case" effectively imply `text-transform: uppercase`, and I’m using such a font, so the entire site is inappropriately uppercase for me.
(The rest of the font-feature-settings declaration also doesn’t make much sense: "case" 1, "rlig" 1,"calt" 0: rlig is for other scripts, and calt is a weird thing to turn off. I’d remove the entire declaration.)
