📚 Description

We have an SSR-styles plugin that removes explicit stylesheets when developing. However, this was not removing them when they include an optional @fs param in the path (which seems triggered when path to CSS isn't the same as the path to root, such as with a custom srcDir or in a monorepo). This updates the code so we remove these stylesheets too.
