crwcln/blockbuilder ? reverse-engineered prompt

Build me a browser app for people tearing down engines, where they can pick an engine from a big library and get a guided, step by step teardown plan. I want it to feel like a practical workshop companion, with a current project bar, a library of engines and small engines, and a simple way to add a custom engine if it is not listed.

It should also walk the user through taking photos from the right angles, save those photos on the device, let them add notes, and then ask AI to review the photos for missing shots, blurry images, wear, and damage. Please include VIN lookup so someone can paste or scan a 17 character VIN and get the closest match, plus an easy way to add a license plate to a project. Make it installable on mobile and work offline for everything except the AI chat and photo review. If you need to look up current docs online, go ahead.
