What is the best solution for html-layout without react/vue?

[Poylar]

Hello. I really like vite for its simplicity and speed, unlike webpack, it brings me only joy.
I can't decide what the best solution would be for developing a simple html-layout . That is, under the CMS.
Usually I would like to use something like pug/ejs/njk , but I need some kind of html framework that supports imports and other cool stuff.
In my recent project, I tried to use pug, but I don’t really like the idea of ​​​​duplicate first html pages, then connect pug inside them, it would be more convenient if vite itself defined the entry point as a pug file.

The problem is that if you add more pages, it will be too much.
What configs do you use to create a simple MPA without using jS frameworks. Thanks
