v2.1.0

Minor Changes

• #139 025dd2c Thanks @tenphi! - Add Shadow DOM support: useStyles, useGlobalStyles, and computeStyles now accept a root option (Document | ShadowRoot) to inject styles into a specific shadow root. Styles are injected via adoptedStyleSheets when targeting a shadow root, with a shared ChunkSheetRegistry for deduplication across multiple shadow roots.

Patch Changes

• #139 4b8bd9d Thanks @tenphi! - Use happy-dom for injector tests, removing mock CSSStyleSheet and adoptedStyleSheets shims

• #139 8f6c8fe Thanks @tenphi! - Make SheetInfo.sheet nullable to accurately represent adopted mode where no HTMLStyleElement exists
