So this looks like an issue coming from vite-plugin-svelte? I think what's happening is it's trying to preprocess everything inside of the src/ directory.

Is there a reason your templates need to be inside of src/? Do all of these templates need to be built?

Putting the templates @ the project root seems to work as a workaround, just thought it was a weird issue and am wondering if other valid source code could cause the same type of issue.
