A container query on the scroller, once, so a new section is responsive by being in the column rather than by remembering to say so. Below 320px the two-column sections stack instead of truncating every select to "Martia…". Colors stays flex-wrap: three swatches in a two-column grid is 2 and 1.

/**
|
|
* Where an editor opens — a column beside the preview rather than a drawer beneath it.
|
|
*
|
|
* It was rendered under the frame, which took the height from the thing being edited: choosing a
|
|
* spacing shrank the page you were choosing it for, and on a laptop the preview lost a third of itself
|
|
* to a row of two dropdowns. A panel keeps the page whole and puts the controls where a workspace puts
|
|
* controls.
|
|
*
|
|
* It holds nothing of its own except the width. The panel that owns a selection builds the editor and
|
|
* announces it — see useEditorSlot for why it carries the element rather than a description of one.
|
|
*
|
|
* ── The device toggle is here, above everything ──
|
|
*
|
|
* It was in a bar across the top of the detail panel, which put it beside Sync and Publish — three
|
|
* things that act on the SITE next to one that decides how you are looking at it. It belongs with the
|
|
* settings it scopes: a spacing is chosen per width, and the control saying which width should be the
|
|
* first thing in the column those choices are made in.
|
|
*
|
|
* Always drawn, including when nothing is selected. It is not part of the editor — it decides what the
|
|
* PREVIEW shows, so hiding it until a block is picked would mean selecting something to change the
|
|
* width and then deselecting it.
|
|
*
|
|
* It reads `?device=` rather than a context, which is what lets it live in a panel that is a sibling of
|
|
* the one holding the preview. See DeviceToggle.
