/* POS screen (PosLayout + Pos.razor). The screen is exactly one window tall and the page never scrolls: only the
   product grid and the cart lines scroll, each inside its own panel. Products take the wide side, the cart the
   narrow one; on a phone the cart becomes a sheet that slides up from a bar at the bottom. Highlights and buttons
   use the app's purple (#7539FF, the theme's btn-primary). Logical properties, so Arabic and Kurdish mirror it. */
