/* AI Fly Brain: only what is particular to this page. Shared layout, type and
   colour live in /css/lab.css.

   page.js reads a few custom properties to draw with. The charts sit on white
   sheets, so --line/--dim/--accent are paper colours; the neuron view sits on a
   pale plate, so --dot is a faint ink. */
