/* A native checkbox is only about 22px, too small to hit reliably while
   packing one-handed. The label carries the tap target instead, so tapping
   the item name toggles it. Controls that are not the checkbox – the bag
   picker, rename, delete – stay outside the label, or tapping them would
   toggle it too. A quantity item uses the same grouping as a plain span,
   since there's no boolean to tap-toggle, just a number to type into.
   min-width is a floor, not 0: with more controls on a row than fit at
   375px (a quantity item's number input plus its own extra button), a
   floor of 0 let this shrink to nothing and wrapped the name one letter
   per line. A real floor makes the row wrap the *trailing* controls onto
   a second line instead, which is what flex-wrap on .row is there for. */
