sandeep-sivan/angular — reverse-engineered prompt

Build me a full Angular style development platform for creating mobile and desktop web apps with TypeScript and JavaScript. I want this to feel like a real framework repository, not just a sample app.

Please include the core framework pieces people would expect, plus a documentation site, a quick start experience, examples or integration coverage, and solid tests so it feels production ready. It should also look like a serious open source project with a changelog, contribution guidance, and the usual automation for building and checking everything.

Keep the structure clean and scalable since this is a bigger codebase with multiple packages and docs living together. Make sure someone could clone it, install dependencies, run the main build, run tests, and browse the docs without a lot of confusion.

If you need to, look up current Angular docs and public expectations online so the overall shape and developer experience feel familiar.
