  description: "One hard vertical edge dividing two fields at different charge. Cool granular teal on the near side with the grain densest against the boundary; warm diffuse amber on the far side holding a single small lit nucleus. A rippling thread carries the discharge in the reflection below, on the warm side only."
  visual_qualities: "hard-edged, granular, two-temperature, tiny-nucleus, no glow spill, reflected thread"

  notes: "Commissioned as a design reference rather than as page decoration, and it changed the code: systems/arrival-electrostatics.css drew a ring around the whole seat with a soft inner bloom until this render showed the boundary is one side, the charge is grain concentrating toward it, and the nucleus is roughly one percent of the frame. The CSS now matches. When a discharge treatment drifts, compare against this."
