/**
 * Time picker — an hour column and a minute column, the dropdown of
 * `mud-time-input` (Figma Time frame 13807:8471, dropdown 13810:9450).
 *
 * The selected value of the column being edited is solid (`.day-cell` Active);
 * the other column's selected value is tinted (`.day-cell` Middle). Picking an
 * hour moves on to the minutes while no minute is chosen, and stays on the hour
 * when one is; picking a minute completes the time and fires `mudChange`.
 *
 * Keyboard: each column is a listbox with one tab stop. Up / Down move within a
 * column, Home / End jump to its ends, Left / Right switch columns, Enter or
 * Space picks the focused option.
