Module app 

The canvas side of the demo: frame pacing and egui painting.

Session pairs the Controller with the presentation state a frame needs (pace, reduced motion, cached texture and observation). Its Session::show paints into any egui::Ui, so the full paint path runs headless in tests; the browser shell only forwards frames to it.

Structs

Session

The controller plus everything a frame needs to present it.

Enums

Pace

How quickly a running study advances. Every pace runs at most one trial per frame.

Functions

split

Splits the canvas into the heatmap and history areas: side by side when the canvas is wide, stacked otherwise.
