/* POS middleware control plane.
   Direction: an operations ledger. The subject is sequences, shifts, time windows and limits,
   so numerics are set in a monospace face (receipt/POS heritage) and the signature element is a
   24-hour band that turns each preset's abstract windows into something you can read at a glance.
   Palette is ink + paper with a single amber "limit/caution" signal — deliberately not the
   terracotta/acid-green defaults. */
