Version 1.4.0

What's Changed

Animation and accent color now follow the WinUI 3 template instead of approximating it.

Changed

• Slide timing — the thumb waits 33 ms, then slides for 367 ms along the cubic Bezier curve 0.1,0.9 0.2,1.0, replacing the previous 150 ms ease-out. AnimationDuration now defaults to 367. The curve is front-loaded, covering 90% of the travel in the first 120 ms
• State transitions — hover, press and disabled changes cross-fade over 83 ms (250 ms into disabled) instead of taking effect instantly. Thumb size and position animate together with the colors, and interrupting a transition no longer jumps
• Accent color — the On track uses the accent color configured in Windows, read from the system palette, falling back to #0067C0 (the Windows 11 default). The previous #0078D4 is the base accent, not the shade the light theme calls for, and #005A9E came from the Windows 10 palette
• Hover and press on the On track — these now lighten the track toward the background by lowering opacity to 0.9 and 0.8. They previously darkened it, the opposite of the WinUI behavior

Fixed

• A click that nudged the pointer by less than the drag threshold left the thumb permanently offset by those few pixels
• Disabling the component while it was pressed left it stuck in the pressed state, because a disabled window never receives the matching mouse release
• A DPI change measured the layout once at the old scale before correcting itself
