Add a fillable government PDF

Government forms are one of the best places to contribute because the path is concrete. A form-backed template lives under templates/forms/..., names the official origin_url, asks its intake questions from the shared question bank in store/seeds/Question.yaml, and maps answers onto the PDF's AcroForm fields through either a .fields manifest or a .fields.toml map. The workflow still passes through staff_review before the filled packet can be signed or filed.
