"""Run a cloud Linux container in Python with the Cua Sandbox SDK.

async with Sandbox.ephemeral(Image.linux()) as sb:

|
Sandbox.ephemeral() without local=True provisions a container on the Cua cloud.
|
|
Requires CUA_API_KEY environment variable. No Docker or local runtime needed.
|
|
|
|
Contrast:
|
|
Image.linux() + local=False -> Cua cloud container (this file)
|
|
Image.linux() + local=True -> Docker container on your machine
|
|
Image.linux(kind="vm") + local=False -> Cua cloud VM
