Most people's mental model of Claude Code is that "it's just a TUI" but it should really be closer to "a small game engine". For each frame our pipeline constructs a scene graph with React then -> layouts elements -> rasterizes them to a 2d screen -> diffs that against the previous screen -> finally uses the diff to generate ANSI sequences to draw We have a ~16ms frame budget so we have roughly ~5ms to go from the React scene graph to ANSI written.
