                            Custom combobox — native <select> dropdowns ignore most CSS on
                            Firefox/Chrome (OS-rendered list); this gives full styling control.
                            combobox.js wires up the keyboard nav, click-outside-to-close, and
                            writes the chosen value to the hidden <input id="id_sea_spread"> so
                            sea.js's existing `spreadSel.value` read still works.
