Canvist paints the editor, one glyph at a time

Field notes

The browser demo lets visitors type into the canvas-rendered editor; the collaboration scene is explicitly labeled simulated, so it is not evidence of live sync. The page describes a Rust core shared across web, desktop, mobile, and cross-platform toolkits, and lists Yjs compatibility. It reports a 0.29-microsecond median keystroke-to-paint time in a 100,000-block document; that performance figure is the project's own claim.
