/*  Source Logistics dock scanners - shared shell.

    Designed for the conditions rather than for a desk: a handheld or a wall tablet, held at
    arm's length, in a cold aisle, by someone wearing gloves and not looking closely. That
    drives most of what follows.

      - Nothing smaller than 16px, and the answer itself is huge. It has to be readable
        without bringing the device to your face.
      - The result card is colour-coded and the colour block is large. Across a dock you
        read the colour first and the words second.
      - Touch targets are 48px minimum. Gloves are imprecise.
      - Dark by default. Screens are glare sources on a dock at night, and this is the same
        palette as the KPI app so the two do not look like different companies.
      - No hover states carry meaning. There is no mouse.
