Address remaining code review feedback

1. Restore SSR parity: Component now returns inline <style> element
   during SSR instead of null, maintaining behavior with original
   createGlobalStyle which rendered during SSR. This prevents flash
   of unstyled content.

2. Fix misleading test name: Renamed test from "only creates one style
   element" to "creates a separate style element for each component
   instance" to accurately reflect the actual behavior.

3. Update test comment: Changed "still only one style element" to
   "each instance creates its own style element" to match assertions.

4. Update SSR test: Changed test name from "renders nothing" to
   "renders style element for SSR" to reflect new behavior.
