Performance Improvements

• Bridge/CSS: optimize Blink style engine matching and invalidation (including media-query evaluation and resize-triggered recalc) (#806).
• CSS: skip caching var()-dependent colors to avoid stale cache hits and reduce variable-change overhead (#812).

Bug Fixes

• CSS: preserve author stylesheet DOM order and base URL; fix subtree style recalculation when display:none becomes visible (#806).
• Theme: sync system color scheme changes with Blink prefers-color-scheme media queries and dispatch ColorSchemeChangeEvent reliably (#806).
• Router/Prerendering: mount initialRoute during prerendering and emit a prerendering event for initial router-link (#811).
• Rendering/Widget: avoid unbounded width constraints for widget elements with min-width in unbounded contexts (e.g. Row + Expanded) (#816).
