Declarative CSS Module Scripts

Declarative CSS Modules Scripts are an extension of the existing script-based CSS Module Scripts. They allow for developers to share declarative stylesheets with shadow roots, including declarative shadow roots. Developers can define inline style modules with <style type="module" specifier="foo"> and apply a declarative module to a declarative shadow DOM by referencing specifier or a URL, such as <template shadowrootmode="open" shadowrootadoptedstylesheets="foo">.
