<%# Markup for the time-picker (time selection) demo.
    stimeo--time-picker treats each segment (hour / minute / AM·PM) as an APG Spinbutton,
    handling arrow-key increment/decrement, edge wrap and carry (minute→hour), left/right
    segment movement, and direct numeric entry, and reflects the composed 24-hour value
    (HH:MM) into a hidden input. Each segment is an independent tab stop. %>
