/* ---------------------------------------------------------------------------
   Combobox — a select you can type into, single or multiple.

   A native <select> stops being usable somewhere around fifty options, and
   Ghana's constituency list is 276. A <datalist> would give the typing but not
   the constraint: it accepts anything typed, and a registry where one person
   types "Ayawaso West Wuogon" and the next types "Ayawaso W/W" cannot be
   filtered or counted, which is the whole reason the field is a lookup.

   So: a text input that filters a listbox, writing to a hidden input. The
   hidden input is what submits, so a half-typed query is never mistaken for an
   answer. Multiple mode renders the chosen values as removable chips above the
   input, and submits one hidden input per value.
