Ask HN: Which tech stack for creative blogs?

by creative blogs: I mean ones where you can customize specific article pages easily, to change the styling, add interactive demos, etc..

Examples:

1. this Reuters article https://www.reuters.com/graphics/TENNIS- WIMBLEDON/GRAPHIC/lbvggkzjmvq/

2. anything by Bartosz Ciechanowski

For my blog (yusuf.fyi) I used to MDX to do this, but I have since moved on from the react ecosystem and want something lower level. especially since my site got vendor-locked in an old astrojs version and I am struggling to upgrade it.
