/* Behavision desktop — a shop-floor instrument, not a website.
   ===========================================================================
   Designed for one situation: a PC behind a counter, on a cheap monitor, in a
   room with daylight, glanced at by somebody who is mid-conversation with a
   customer. Everything below follows from that.

   - Dark, because the screen sits in peripheral vision all day and a white
     field at 1000 lux is a lamp pointed at the operator.
   - State is carried by shape AND colour: a pill, a dot and an edge stripe,
     never colour alone. This gets read from two metres away, and some
     operators do not see red and green apart.
   - One spacing scale and one type scale. The previous version set margins
     inline, per screen, which is how a UI ends up looking assembled rather
     than designed.
   - Motion only where it carries meaning: a live camera, a fresh arrival.
     Nothing loops for decoration — this process shares a CPU with recognition.
