"""Start a disposable Celesto browser sandbox.

Run:
    python examples/browser_sandbox.py

Optional:
    pip install playwright

If Playwright is installed, this example connects over CDP, opens a page,
and captures a screenshot. Visible browser sandboxes also expose a viewer URL
for humans and a display URL for VNC-compatible tools.
