FWIW, to me it is just an embedded PDF. Sure, lots of empty space, but not terrible either.

Here's the arxiv: https://arxiv.org/abs/2411.02373

Here it is in dark mode: https://arxiv.black/abs/2411.02373

(Seriously, we need to be offering dark mode more... I just wish the browser's pdf readers would also convert to dark mode and not be so bright. I can't be the only one that likes to read papers at night)

> but the readability of that site is very poor

Would love to hear your feedback and improve it! Could you please tell me more?
