Connected Corners
Describes which corners of a Connected UI item are outer corners (large radius) versus inner/joined corners (small radius).
In the Connected UI layout system, items are arranged edge-to-edge with a narrow gap. Corners that face the exterior of the group use StylishDimensions.connectedCornerRadius (default 12 dp), while corners that face an adjacent item use StylishDimensions.joinedCornerRadius (default 2 dp). This creates the visual "notch" effect where items interlock.
The coordinate system follows Compose layout conventions: topStart is the top-left corner in LTR layouts (top-right in RTL), topEnd is top-right in LTR, and so on.
