"use server" looks like syntactic sugar over a fetch call to an API route – and that's exactly why most implementations treat it like an ordinary function call. That's a mistake with real consequences: every function marked "use server" becomes a public endpoint on the network, and a form built on this mechanism works even before JavaScript has had a chance to load. I look at what actually happens behind that directive, and where the pitfalls sit that the docs don't make obvious at first glance.

Correct HTML is only the starting point. See how the accessibility tree actually works, why ARIA does more harm than good more often than you'd think, and build a real accordion, a live region, and Next.js focus handling with me.
