p5.js + TypeScript. TUIO: mock pointer or WebSocket bridge.

Symbol ID (mock) 0 — ellipse 1 — 0/1 text 2 — triangle Mock TUIO (follow pointer)

WebSocket JSON example: {"objects":[{"symbolId":2,"x":0.5,"y":0.5,"a":0}]} — x,y in 0–1 (TUIO-style origin bottom-left); omit objects for empty frame.

Serial needs Chrome/Edge and HTTPS or localhost. Sends same SxyZE lines as the Arduino sketch.
