An empty dark blue screen, which is the window's own background with nothing
drawn on it. The cause is one name used twice: the veil element carries class
`busy`, and the state was put on the body under the same name - so
`.busy { display: none }` applied to the BODY as well, and the page vanished
the moment any operation started.
The state is now called `is-busy`, which nothing else carries. Checked the
other body states - typing, selecting, searching, on-list, on-detail - none
of them names an element, so none has the same trap.
