web platform APIs का reference — web-dev notebook के लिए भरोसेमंद ground truth।

Maintained by browser vendors and a large contributor community, it's the reference point most developers already treat as ground truth for whether a given API works and in which browsers. That makes it well suited to a notebook that needs to verify compatibility claims rather than take a blog post's word for it. It documents what exists, not how to structure an application, so pair it with a source on architecture or design patterns for that kind of question.
