/*
    The warehouse handset.

    Every measurement here is decided by one fact: this is used one-handed, with gloves on, on a
    cheap Android phone, in a shed. So

      - nothing interactive is smaller than 56 px in its short dimension. A gloved thumb is about
        that wide, and the standard 44 px touch target is sized for a bare finger at a desk;
      - the primary action sits at the BOTTOM of the screen, where a thumb reaches without the hand
        regripping. A confirm button at the top is a dropped handset;
      - Confirm and Discard are never adjacent;
      - contrast is high and type is large, because the screen is being read in daylight through a
        scratched protector.

    Colours are the web client's, not a second palette.
