I am very excited about HTML export! HTML is much better at responsiveness and accessibility.
Typst is such a great software. With it's modern programming language like syntax I learned it much faster than Latex. It's compile duration is also much better in my experience. I am honestly more productive using Typst it this point. Though I am not a power user. I only used it for slides and notation heavy articles.
Exactly. I like to output PDFs with exact layout, and then output to HTML with approximate layout for flowing, ease of use.
To create HTML from typst also have a look at https://myriad-dreamin.github.io/shiroa/introduction.html and https://github.com/Myriad-Dreamin/typst.ts .
