The general look of the page is nice. Two critics:

1. The font is too thin (Firefox on a Samsung A40)

2. I tried to pinch to zoom to compensate but the page doesn't zoom.

Luckily reader mode works. It doesn't look as nice but it's easier to read.

2.5 I'm not sure the left and right margins are needed. If I could zoom I'd have zoomed the text to fill the page.
