font-size-adjust: a foreword for people who aren’t reading from their browser

Hi! Sorry but I don’t feel legitimate enough to amend your post and make a pull request myself. I opened your post on my RSS reader, Akregator 6.4.0, which I never configured how it renders posts. I may also miss some fonts it expects since I have yet to grasp the font packaging situation on NixOS. My hunch would be the latter being problematic, since changing the property still make the first X one pixel lower. In any case this breaks the showcase of the `font-size-adjust` CSS property: <img width="101" height="187" alt="glyph rendering in Akregator 6.4.0" src="https://github.com/user-attachments/assets/b4e6d84a-b086-42d7-9ef3-21a34f04532a" />   So maybe a foreword at the top of your post telling people to read it directly from their browser would be nice? Thanks in advance,
