"""The banner names the desktop shell shape, not just "desktop-app".

An old-style installer artifact (payload ``bootstrap``, mechanism ``self``)
runs its CLI backend from the same stamp as a bundled release build; the
banner must not present both as identical packaged builds — the installer
shell never updates itself, the managed checkout under it does.
