Scripts can now connect to external browser instances at
runtime via import { chromium } from 'k6/browser' and
chromium.connect(wsURL). This bypasses the managed browser
registry entirely - users control the browser lifecycle.
Enables use cases like Browserbase where session URLs are
dynamic and fetched per-iteration from an external API.
No cloud or SM platform changes needed: scripts without
options.browser skip the entire managed browser pipeline.
Shows chromium.connectOverCDP() with an external browser provided via K6_BROWSER_WS_URL. No options.browser needed.

What?
Scripts can connect to external CDP-compatible browsers at runtime without declaring
options.browser.The naming follows Playwright's
chromium.connectOverCDP().Why?
Users with their own browser infrastructure want to run k6 browser tests against their own browsers. Their flow requires a fresh WebSocket URL per session, obtained at runtime via an API call.
