The site uses Astro (https://astro.build/) and the code blocks are generated using Shiki (https://shiki.style/). As Shiki generates the HTML and CSS at build-time instead of requiring runtime JS like alternatives like Prism (https://prismjs.com/#basic-usage), it's actually quite performant. I think it's unlikely that a couple of hundred lines with some empty spans in is going to cause performance issues – imo it's more likely to come from some silly JS somewhere.

There was a silly on scroll listener that was doing basically nothing – I've tried removing that so if you happen to visit again, I'd be very grateful if you could let me know whether it is still happening (I can't reproduce it myself).

Thanks for letting me know. I'm on an M3 and haven't experienced any issues myself, but allowing for font size configuration seems like a pretty good idea. I'd added this in so if you happen to take another look, I'd be interested to hear whether you think this is an improvement.
