Stack: HTML templates and a sprinkle of vanilla JavaScript

What if the "modern" web is overly complex for most use cases? I'm sharing a project, a website for a product studio "Bearle", that was built on what I'd call a "2025 Stack" - a return to simplicity. It's a fully functional single-page application built with:

    No React, Vue, or Angular.

    No Webpack, Vite, or Parcel.

    No npm or bun.

Just plain old HTML <template> elements and vanilla JavaScript to handle routing and dynamic content. The result is a website that is incredibly fast, easy to deploy, and simple to maintain.

Have we gone too far with our complex toolchains? For many projects, is a simple, no-build, no-framework approach like this one a more sensible choice?

What is difference in html size and page performance in comparison with React + Vite, for example?
