bcgov/HOUS-Interactive-BCBC ? reverse-engineered prompt

Build me a clean web app for the BC Building Code that people can use to quickly search and browse the code without any backend.

It should let users pick a code version, search the full text instantly, and move through the content in a simple hierarchy like division, part, section, and article. I want the selected version to stay in the URL and remember the user’s choice, so links can be shared and bookmarked. It should also support clicking on defined terms to jump to their meanings, and let people filter by effective date where that matters.

Please make it responsive for desktop and mobile, and accessible to a very high standard. Use a modern static site approach with TypeScript and a good component system, and keep the content loaded from generated files so the whole thing works client side. If you need current docs or best practices for any piece, look them up online first.
