CustomElements library bundle size is significantly larger than the docs state.

Here's what it says in the docs:

When building custom elements with Vue, the elements will rely on Vue's runtime. There is a ~16kb baseline size cost depending on how many features are being used.

In my local environment I was getting a bundle a lot larger than that, even though there wasn't a whole lot happening in the actual library code, so I got suspicious about that number in the docs.

So I've created a minimal sample project on stackblitz to test my theory. Which is barebones Vite + only 2 empty Vue components building as a custom elements library - and they're literally empty, just a single <div /> in each of them.

And here's what it builds:

dist/output.js  150.92 kB │ gzip: 46.35 kB 
dist/output.umd.cjs  101.04 kB │ gzip: 37.39 kB

That's a bit more than 16 kb, even compressed. Maybe we should modify the docs because that looks misleading.

Start with the linked Custom Elements library documentation and reproduce the linked StackBlitz sample using src/main.js, vite.config.js, and the two component files. Compare the reported bundle sizes with the documented baseline; done means the documentation accurately explains the expected size or is updated to address the discrepancy.
