ca61aca: Fix CSS block comments containing // (e.g. URLs) causing subsequent styles to not be applied.
a2cd792: Fix createGlobalStyle styles not being removed when unmounted in RSC environments. React 19's precedence attribute on style tags makes them persist as permanent resources; global styles now render without precedence so they follow normal component lifecycle.
dbe0aae: In RSC environments, theme is now undefined instead of {} for styled components, matching the existing behavior of withTheme and createGlobalStyle. This ensures accessing theme properties without a ThemeProvider correctly throws rather than silently returning undefined.
1888c73: Fix withTheme HOC types: ref now correctly resolves to the component instance type instead of the constructor, and theme is properly optional in the wrapped component's props.
f84f3fa: Fix SSR styles hydration and global style cleanup in Shadow DOM
43a5b4b: Optimize internal style processing hot paths: cached GroupedTag index lookups, string fast path in flatten, direct string concatenation in dynamic style generation, pre-built stylis middleware chain with lazy RegExp creation, single-lookup Map operations, VirtualTag append fast-path, and manual string concat in SSR output.
788e8c0: Revert exports field and restore browser/server build split with browser field in package.json. Fixes require('stream') resolution errors in browser bundlers like webpack 5.
