"""Autorouting for freeroute.

An MVP grid-based maze router and the DSN-in / SES-out pipeline that makes
freeroute a Java-free replacement for the ``freerouting.jar`` step::

    from freeroute.route import route
    ses_text = route(dsn_text)

The router (:class:`GridRouter`) is intentionally simple — single-layer A* over
a uniform occupancy grid, enough to reach connectivity on boards whose nets
route without crossing. FreeRouting's free-space expansion-room maze, rip-up,
multi-layer via search, and shove are deferred.
