/* ---- desktop -----------------------------------------------------------
   Mobile is the primary surface: most buyers are on a low-end Android phone.
   But the app is also shown on laptops - to partners, and to sellers managing
   listings - and a phone column stranded in the middle of a monitor reads as
   unfinished. So above 760px the bottom tab bar becomes a top nav row, the
   grid widens, and the product page splits in two.

   Body is laid out with flex + order on desktop because the tab bar sits after
   <main> in the DOM (correct for mobile, where it is fixed to the bottom) and
   needs to appear above it here. */
