A container query, not a screen one: this sits in a workspace panel whose width
is a divider somebody drags, so the window says nothing about the room. Below
240px the icons stand alone and the word is the tooltip.
Every editor section starts open. It opened on one, from ?tab=, which is what
tabs want — these are not tabs, and a collapsed column asks somebody to go
looking for the setting they came for. ?tab= is gone with it.

Icons alone told three things apart by proportion at 12 pixels. Full width, one
of three filled, and the word from DEVICES.
The `size` prop is gone with the bar that needed the small one, and so is the
second copy inside Spacing — the panel header scopes the whole editor now.

Spacing's settings are per width, so the section has to say which width it is editing — and the answer
must be the one the preview is already showing, not a second selector able to disagree with it.
It reads `?device=` rather than the ViewMode context, and that is not a preference. The editor is a
SIBLING panel: an element built inside the detail panel resolves context where it is RENDERED, so a
toggle handed over would look up a tree with no provider in it and quietly show the default forever.
The URL is the shared state, which means there is nothing to share. Three components read one
parameter, so they cannot disagree, and the preview follows without being subscribed to anything — it
reads the same value. More editor sections can take the control by rendering it.
The bar's own toggle is now the same component. It had its own copy of the options and the handler,
which is exactly how two controls for one thing start to differ.
