Include app.css in custom error.html file

[kevinrenskers]

I have an app.css file in my /src folder, which I simply import in my root layout import "../app.css". Now I want to create my own custom error.html file, and I want to include the same base app.css file, but there is no static URL for it that I can import. If I move app.css to the /static folder I can easily include it from the custom error.html file, but then I can't import it anymore from my root layout. So then I'd have to include it in the app.html header myself and it won't get bundled, I don't get HMR when making changes to the file, etc.

So other than duplicating this file, what other options are there for sharing the base css between the site and the static error page?

One option is to create a route, say routes/app.css/+server.js, that you use to serve the css file.
