"""Default project entry point.

The CLI itself lives in :mod:`app_cli`. This file exists to define the
project's preferred generator configuration, especially the weighting of the
soft constraints.

To customize the generator for experiments, adjust :func:`build_constraints`
below and run::

    python3 code/main.py --form sentence --pdf

The rest of the command-line workflow, including parsing, rendering, and
rerender mode, is handled by ``app_cli.run_cli``.
