Reader mode is the way but tbh after the first 1500 words or so I didn’t know where it was going. I’m old and life is short,

I agree. Horrible writing. For a while I thought it's just some LLM output.

Not worth reading anyway, so you've lost nothing, OP.

Bless

You can use Reader mode on Firefox

Not only does Reader Mode work beautifully, but, colour choice notwithstanding, the article's CSS styling is sufficiently vanilla that my own enhanced Reader Mode stylesheet (drop caps and a few other fiddly bits) works beautifully. That's often ... not ... the case.

I think it is a good font color. Nice contrast.

Also if you're the sort that cares enough about such things to make a post complaining you should have tools to change them or override per your preferences (e.g. reader mode).

It's high contrast, better than a lot of websites. You'll be fine.
