/* The six plates do not share a camera. Chart and dividers are drawn near
   plan view; the bucket is about 40 degrees; rubble, jar and sounding lead
   are side-on or hanging. Objects at different eye levels may sit NEAR each
   other on paper, but they cannot OVERLAP without reading as collage — so
   the stage holds only the two plan-view plates plus an adjacent bucket,
   and the rest become marginalia further down.

   The stage is bounded, and its height comes from the chart's intrinsic
   aspect ratio rather than a magic number. The satellites are anchored in
   percentages OF THE CHART, so the composition scales to the 320px floor
   without a second layout, and survives an editorial change because there
