I really like go, but the rest of what you're using is just so wasteful.

Though what might be a lot more helpful would be if you put copies of the files somewhere. It's often easier to follow if you have the whole thing, not snippets to try and copy/paste together.

A live demo would be even more impressive. It's one thing to talk about what can be done, it's something different to show it in its entirety.

Also try and ease up on the DIV soup. :D Bad enough you've got the HTMX trash in there.

Oh and "just like an SPA"? No. It IS an SPA. In all its "wah wah teh pageludz r teh evuls" paranoia and middle finger to accessibility and usability glory.
