/* LIGHT TREATMENT (research workspace): the separation mechanism changes from
   luminance to material — hairlines alone on white read as unloaded, so the answer
   list becomes one white sheet with internal hairlines. The rail loses its fade (a
   fade to transparent on white reads as an artifact) and its head becomes a solid
   segment. The log node inverts figure/ground: white fill, ink ring. Depth arrives
   as a short shadow, which dark cannot use at all on its near-black canvas. */
