ADR 0515 §4, §5: the trusted setting modes names the accounts Work and Personal show, Everything shows every
granted account; /read shows one mail as escaped text with its tasks, promises and attachments as downloads,
records it opened, and offers its corrections (mark and group, not a task, not a promise, read later), each
calling correct. Issue 1850: a sender with no display name is named by its address, on the list, the pane and
All mail.
A program cannot import a main package; the page's code moves to modules/mesh-mail-web/internal/web, and

Nothing the module does changes.
