What this replaces. The current app runs two navigation systems at once — a seven-item pill row that scrolls off the right edge of a phone, and a six-icon floating dock that covers the credential cards behind it. Both offer the same destinations.
Why Add sits in the middle. It is the only thing here that is a verb. Giving it the centre slot, raised and filled, means capture is always one thumb-reach away — and it never has to compete with a floating button for the same corner.
