/* CloudyERP prototype — hero (W5)
   Editorial split: copy + the operation chain on the start side; one flagship CloudyERP operations window on the end side,
   with the POS phone in the foreground and a ghost window behind it. A single signal trace runs from the till through
   every pane (sale lands → stock → ledger → management) and closes the loop.
   Compositions share one DOM: wide (≥1181px) · tablet (761–1180px, same canvas scaled) · mobile (≤760px). */
