Browser automation/testing with BiDi and minimal dependencies
summary
Demonstrates that WebDriver BiDi is a W3C draft streaming JSON protocol already implemented in Firefox and Chromium and usable with only the installed browser plus websocat or python-aiohttp no npm or Selenium required. Shows a 600‑byte counter page, gets the browser WebSocket URL, subscribes to log events, navigates, locates a button with a CSS selector, performs pointer move/down/up to click, and uses script evaluate to read the span. Supplies toy shell scripts and a ~500‑line Python library used in Cockpit and the demo works on both Chromium and Firefox.
