/* Cashier POS licence admin - rebuilt mobile-first.
   The panel is used far more from a phone than a desktop, so phone layout is
   the base and wider screens are the enhancement. Notably there are no
   horizontally scrolling tables: subscriber records render as cards, which is
   what made the old table unusable on a narrow screen. */
