 PageLayout: Optimize drag/resize performance with inline styles and new optimizations
 
 **Refactored:**
-- Apply CSS containment via inline styles instead of `[data-dragging]` attribute selectors (O(1) vs O(n) selector matching)
+- Use direct attribute selectors (`.Pane[data-dragging='true']`) instead of descendant selectors for CSS containment (O(1) vs O(n) selector matching)
 - Extract optimization utilities to `paneUtils.ts`
-- Use CSS variable for drag handle visual feedback
+- Apply drag handle visual feedback via inline styles and CSS variables
 
 **Added:**
 - `content-visibility: auto` during drag/resize to skip off-screen content rendering
-
 - rAF throttle for drag updates (one update per frame, latest position wins)
 - Containment during window resize (parity with drag)
 
-**Removed:**
-- `[data-dragging]` attribute and associated CSS descendant selectors
-
 These changes improve style recalculation performance on large DOMs (100k+ nodes) by eliminating descendant selector traversal.
