Ask HN: can we fix the tiny HN font size?

With Chrome on Android, reading HN is really hard for us with failing eyesight. The fonts are tiny and the only solution is to either scale the text size up massively, which breaks all other websites, or continually pinch to zoom, which means lots of left to right scrolling to read a full comment.

How hard would it be to offer a font size option in the user preferences?

I understand that most HN readers are young and have excellent eyesight, yet this is a real accessibility problem.

Afaics it's been like this for years. HN, pretty please, it is dicriminatory. Can we fix this now?
