    | own POST actions through fortify.domain — is bound to this host and does

    | than a working page, which is the point: a route belongs to a hostname,
    | and a route that is not registered for the host being asked cannot answer.

    | host-agnostic — so the website vanished from the portal, and the portal

    |  - ÖFFENTLICH: `storage/app/files/public/`. Anonym abrufbar, indexierbar.

    |    ein 404 statt eines 403 — dieselbe Regel wie bei der Konsole: ein
    |    Fremder soll nicht erfahren, dass es das hier gibt. Das Archiv liegt in
    |    keinem Verzeichnis; es wird bei Bedarf aus `deploy/bootstrap` gebaut.
    |

    | app.clupilot.com got the shop window: marketing copy, a pricing table and
    | a "sign up" call to action, at the address where their servers are.

    | Set, the website — landing page, robots.txt and the legal pages — exists
    | on these names and nowhere else. Every other host answers "/" with the
    | product instead. The console keeps its own "/": its routes are registered
    | first and win.
    |
    | Binding the legal pages is also what makes route('legal.impressum')
    | produce a canonical URL from inside a queued mail, where there is no
