look.js holds the canvas's visual language. A host is a square, a session a diamond and a subagent a dot; each is white-hot when it has just spoken, solid in its operator's hue for a minute or so, hollow by five and a ghost by fifteen. Operators wear a tick dial with a tick per agent, lit for the ones at work. A graticule sits under the plate, emoji hang beside their agents as cached sprites (only the latest few dozen when pulled back), and the glow sprites are gone, which roughly doubles the frame rate at 420 agents.
