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
Same stacked-sheet idea as Still: ancestors wait underneath as colored layers. Move near the top or left edge and this sheet peeks open so you can feel the stack; click to slide it all the way back and step into a prior place.
