   Counter POS (/pos) on the gm design. Full screen, no ERP sidebar: top bar, sale header,
   then the product grid and the cart side by side. Only the grid and the cart lines scroll;
   the page itself never does. Controls stay touch-sized (40px) for counter screens.
   Anchored on #gm-pos (PosLayout) and #gm-pos-login (login page).
