"""Browserbase cloud browser provider — plugin form.

Subclasses :class:`agent.browser_provider.BrowserProvider` (the plugin-facing
ABC introduced in PR #25214). The legacy in-tree module
``tools.browser_providers.browserbase`` was removed in the same PR; this file
is now the canonical implementation.

Browserbase requires direct ``BROWSERBASE_API_KEY`` and ``BROWSERBASE_PROJECT_ID``
credentials. Managed Nous gateway support has been removed — the Nous
subscription now routes through Browser Use instead (see
``plugins/browser/browser_use/``).

Config keys this provider responds to::

    browser:
      cloud_provider: "browserbase"

Auth env vars::

    BROWSERBASE_API_KEY=...       # https://browserbase.com
    BROWSERBASE_PROJECT_ID=...

Optional feature knobs::

    BROWSERBASE_BASE_URL=...      # default https://api.browserbase.com
    BROWSERBASE_PROXIES=true      # default true
    BROWSERBASE_ADVANCED_STEALTH=false
    BROWSERBASE_KEEP_ALIVE=true   # default true
    BROWSERBASE_SESSION_TIMEOUT=... (seconds, integer, max 21600 = 6h)
