@alex I'm curious about the choice of Next.js.

Next.js is a great framework for complete applications where you are rendering pages by pulling from a database, but this appears to be a marketing website with blog posts that are generated from static markdown. It shouldn't be shipping any JS to the client at all, but a quick glance shows almost 300 kB.

Perhaps a static site generator like Astro, 11ty or Hugo would be a better choice?
