// The data of the two signed-out pages, sign-in and first-run setup. Neither has
// a user, so their Meta carries a Title and nothing else: Engine.Render then
// draws them with layout_signed_out, the split brand / form screen, and the
// page template supplies only the form column's content.

// Login is the data of the sign-in page (templates/login.html). Host is the
// name the panel is served as, shown above the title so the person knows which
// server is asking for a password; it is left out when the name is not known.
// SetupHint replaces the form by a pointer to the one-time setup link, for a
// panel that has no administrator yet. Error is the refusal of the last attempt
// ("Too many attempts…"); the page shows it as a flash above the fields.
