/* ==========================================================================
   CHLADNI — figures of sand on a struck plate
   ==========================================================================
   Dust a plate with sand and bow its edge: the grains flee everything that
   vibrates and gather where the wave stands still. Ernst Chladni, 1787.

   Lane        : generative — every figure is computed live, never an image
   Constraints : maximum 2 colours + 1 accent · no boxes (space, rules & type)
   Faces       : Doto (a name in grains) / Geologica / Azeret Mono
   Schemes     : dark default (the blackened plate) · light (the lab bench)
