/*
 * THE EDITABLE COMBOBOX — an input group that IS the control, with the listbox
 * below it. The shell paints the field and owns the ring (`:focus-within`, §2.3),
 * so the leading glyph and the trailing ✕ / chevron are flex ITEMS. The open state
 * wears the SAME ring keyboard focus does, so a pointer-opened field never reads
 * as a lone 1px edge.
