Re: [csswg-drafts] Proposal: CSS @sheet (#11509)

@mhochk 

Container style queries with CSS custom properties work `@sheet`-like in DSDs as you describe.

At least for me in Chrome!

And I am guessing that as [container style queries](https://developer.mozilla.org/en-US/docs/Web/CSS/@container#container_style_queries) grow beyond [just testing for custom CSS properties](https://caniuse.com/css-container-queries-style), there will be even more ways to enable this technique, say by a CSS selector checking for an attribute on the :host?

To me this implies that even if this is indeed a viable `@sheet`-like approach, the core unsolved issue for sharing styles across Declarative Shadow DOMs remains of how to [enable references](https://github.com/whatwg/html/issues/11019) to inline <style> elements and [related](https://github.com/whatwg/html/issues/7540) [caching](https://github.com/whatwg/html/issues/9232#issuecomment-2762763257), [instancing](https://github.com/w3c/csswg-drafts/issues/11509#issuecomment-2657632448) and aligning with [declarative CSS modules](https://github.com/whatwg/html/issues/10673) issues.
