Introducing the refreshed widget

The widget got a visual refresh. Responsive sizing adapts to the viewport: up to 704px tall and 400px wide, with 24px border radius. On mobile viewports under 480px, the widget expands to fullscreen and hides the trigger button.

The colorful pinwheel logo has been replaced with a clean B&W brand mark that uses currentColor, so it adapts to light and dark themes automatically. Dark mode also gets a deeper box shadow for better contrast against dark backgrounds.

The open animation now blooms from the trigger button's corner, giving it a natural feel. The footer is more compact and the message input has tighter padding.
