You could have made it faster and less bloated in just plain HTML, an entirely unecesary level of bloat for a page like this. Your page makes 71(!) requests (compared to HNs 7) and is about ~158kB of data, not far of 3x more data than HN.
You've made something, but not something brutalist, performant or bloat free.
