DOCS: PRSSI (Path-relative style sheet import) fix when using sveltekit

[jjones315]

Describe the bug

This is likely more of a docs issue than a bug, but i dont see a issue template for docs, and i feel bug is closer than feature request, sorry if this is wrong.

Had our website flagged for PRSSI by a security scan and slightly stumped on the optimal way to fix it.

Adding a base element to our site will break several things since right now paths are relative to the current page, and also i don't see a clear way to add a env specific base element in to the top of the html, using svelte:head places it after the style imports by default.

reading the docs i see mentions of assets and base in the docs but base is for relative paths and assets doesn't seem to affect style sheets.

files in /public and js files are using the absolute path correctly. but for some reason styles are not working the same

i tried adjusting the roll up options in vite, but the asset outputs are overwritten by the svelte config.

Have you tried configuring the SvelteKit paths.relative setting? https://svelte.dev/docs/kit/configuration#paths
If you set relative paths to false, the stylesheet imports will be absolute paths
