+## 🚀 What's New in v1.0.3
+
+### ✨ Highlights & Gesture Fixes
+- **👆 Browse Feed Two-Finger Swipe Refresh**: Relocated two-finger downward swipe refresh gesture from the video player to the main browse feed grid (`BrowseGrid`), featuring tactile haptic feedback and a top-center glassmorphic **"Refreshing feed…"** badge.
+- **⚡ Non-Blocking Edge Volume & Brightness**: Narrowed volume and brightness edge drag zones in the player from 20% down to precise `48.dp` side margins with a drag threshold (`abs(totalDragY) > 16f`), reserving 85%+ of screen width for uninterrupted vertical swipe-to-next video paging.
