/* ------------------------------------------- the setup that used to be here
 *
 * The simulator panel carried the whole of the setup: the challenge, the
 * table, the wheels, the attachment and two checkboxes, in a strip above a
 * 3D view that had no room for them. Every one of those is on the field
 * page now, next to a picture of the field it applies to — which is where
 * a decision about a field belongs.
 *
 * HIDDEN, NOT DELETED, and that is deliberate. Those controls are what the
 * field page WRITES: "Open simulator" sets them and fires their change
 * events, and everything the application does when a challenge changes
 * hangs off exactly that. Removing them would mean a second path into the
 * simulator and a second copy of what a scenario means. They stay in the
 * page as the wiring between the two, and stop being furniture.
 */
/* OUT-RANKING THE SHELL, which places this strip with
 * `#workspace-view.xp-shell .sim-setup` — an id and two classes, which
 * beats a bare id however much later it is loaded. Specificity is not
 * settled by file order and it caught me: the rule was written, the strip
 * still showed, and the DOM said `display: flex`.
 *
 * The `hidden` attribute is not enough on its own either. Something in the
 * shell clears it, and a stylesheet that only works while an attribute
 * happens to be set is a stylesheet waiting to stop working. */
