Subject: [PATCH] Use platform-specific selector for Windows scrollbar styling

Instead of modifying scrollbar width globally, use body[os='windows'] selector to apply wider scrollbar (10px) and spacing (2px transparent border) only on Windows platform. This addresses the window resize handle overlap issue specifically on Windows while maintaining the original scrollbar width (5-6px) on other platforms.
