Demo · Variant B
Context Edge
Navigation context lives at the screen edge — color and motion show where you are and how you got there, so the page can stay focused on the work instead of a growing suite header.
Modal Edge
Your current page is a sheet sitting on top of where you came from. Click the top or left edge to slide this sheet back — earlier places stay underneath as tinted layers, so you can step back without hunting a back button or a stuffed suite header.
