"""
JMAP calendar support for python-caldav.

Provides synchronous and asynchronous JMAP clients with the same public API as
the CalDAV client, so user code works regardless of server protocol.

Basic usage::

    from caldav.jmap import get_jmap_client

    client = get_jmap_client(
        url="https://jmap.example.com/.well-known/jmap",
        username="alice",
        password="secret",
    )
    calendars = client.get_calendars()

Async usage::

    from caldav.jmap import get_async_jmap_client

    async with get_async_jmap_client(
        url="https://jmap.example.com/.well-known/jmap",
        username="alice",
        password="secret",
    ) as client:
        calendars = await client.get_calendars()
