Documented steps
POST https://api.browserbase.com/v1/sessions with X-BB-API-Key: <key>.
Capture seleniumRemoteUrl and signingKey from the 201 response (both required for HTTP remote connections).
Point your WebDriver at seleniumRemoteUrl as the RemoteWebDriver server URL.
Authenticate HTTP connections with signingKey (Browserbase uses it to authorize the remote session).
Drive the remote browser via Selenium normally.

Known gotchas
seleniumRemoteUrl and signingKey are both mandatory for Selenium connections; missing either fails handshake.
The signing key is returned once at creation; store it if you need to reconnect.
Selenium remote mode has a CDP inactivity timeout similar to other connections; keep traffic flowing or enable keepAlive.
