The toolbar's search field now lives in AppKit's own NSSearchToolbarItem:
em(17) is the focused width (preferredWidthForSearchField), the resting
width is the item's own, and ⌘F becomes beginSearchInteraction — one call
that expands and focuses. Escape's empty-field exit collapses the field as
the keyboard leaves. resignsFirstResponderWithCancel is off so the staged
Escape survives the cancel button. The item ships its own live overflow row
and an above-.high visibility priority, so both custom-view workarounds
retire. The palette copy stays inert through an enablement round-trip the
item's searchField setter would otherwise overwrite.
The centering half of the card is blocked on a Design ruling (03 settles
"trailing") and is not built; the two-homes width question is filed.
