The shell.

One shell over the whole app: six circular chips on a floating rail — Dashboard, People, Work, Chat, Money, Mktg — with the Boardroom in its own footer group, and pill-segmented floor strips inside each app. The top chrome is deliberately three controls and nothing else: search, the “E.” door with its autonomy ring, and your avatar. Organization and Account live in the avatar menu rather than taking rail space; Files is a floor of Organization.
