Left at the Scarecrow - a corn maze passport where every right answer is the right turn

Grow a seeded corn maze with exactly one way through and checkpoint posts at the forks on that way, then paste a few facts - one per line. Free in the browser: the maze (small, medium or large), three to ten posts with each post's right turn worked out by the page, a walk-it-on-screen mode, a blank printable passport with an answer key, and Markdown, JSON, CSV and SVG exports. One metered task writes the passport: every line sorted into usable facts or left out with a reason, a verdict (ready to print, short of facts, no usable facts), one question per post with the right answer taken from its fact line and two plainly wrong answers, a maze name and entrance and exit signs. The page pins each right answer to the turn that leads on and each wrong answer to a dead end, so a new maze reuses the same questions, and re-checks every reply against your lines.
