useWhen: an editing mode should be announced by motion alone

Hold an icon on an iPhone home screen and everything starts to shake. Apple has never
given the state an official name, so users named it: jiggle mode, wiggle mode, the
wobble. Mechanically it is a tiny rotation oscillating around zero, a degree or two
each way at four or five cycles a second, with a small phase offset per icon so the
screen reads as a crowd of nervous objects rather than as one animation applied eight
times. A delete badge appears on each item at the same moment, and the icons become
draggable.

The reason it works is that a mode is an invisible thing and this one is not. In every
other state on that screen, nothing moves; the moment anything moves, the screen is in
the other state, and the boundary is legible from across the room without reading a
word. It also scopes itself for free. Items that wobble can be rearranged and items
that stay still cannot, so the animation is simultaneously the mode indicator and the
map of what the mode applies to, which no label in a corner could manage. The gesture
in and out is worth noticing too: entry is a [long press](/long-press), a held
gesture, which is the closest a touch screen gets to a quasimode, and exit is an
explicit Done rather than another hold, because a mode you leave the same way you
entered is a mode you will leave by accident.

The lesson generalises past home screens. Any interface with a rearranging state can
borrow it, and the same three parts travel: the motion says which state you are in, an
affordance appears on each item saying what is now possible, and a clearly labelled
exit ends it. What does not travel is the wobble as the only signal. Continuous motion
is exactly what a reader with `prefers-reduced-motion` set has asked not to be shown,
and it is invisible to a screen reader in any case, so the mode has to be announced in
at least one other register: the badges, a changed toolbar, a status line, a live
announcement. Build it so that switching the animation off leaves an interface that
still says what state it is in, and the wobble becomes the delightful part rather than
the load-bearing part.
