tc39/ecma262 ? reverse-engineered prompt

Build me a simple documentation site for the ECMAScript language spec, like the current draft of JavaScript’s standard.

I want it to show the full spec in a clean readable format, with sections, tables, and linked reference pages, and it should be easy to update from the source file so the site can be rebuilt whenever the spec changes. Include a homepage that explains what the project is, where to read the latest spec online, and links for proposal status and related notes. Also add the extra reference pages for things like Unicode property tables and withdrawn proposals, since those seem to be part of the project.

Make it easy to work on locally, with a build command and a watch mode so changes refresh automatically. If you need to check the latest docs or formatting conventions, look them up online first. Keep it polished, readable, and organized for people who want to follow the standard or contribute to it.
