Mockup

Inbox

The whole app-open experience. Every message lands in the inbox directly — no gate, no deck. A header view switcher (Inbox / Sent / Archive), filter tabs, live rows, compose FAB; bottom tabs route between Inbox, Rules, and Settings. Mailbox scope is a separate axis, chosen from the bottom-center Domain Home button (see the domain-home mockup), so it never crowds the header.
