techlovework/emailextractor — reverse-engineered prompt

Build me a simple web app called Email Extractor. I want a clean page where someone can paste in a big block of text, notes, copied web content, or messy data and have the app pull out all the email addresses it can find.

Show the results in an easy to read list, remove duplicates, and give a total count. Add a button to copy all extracted emails at once, and if it makes sense, let people download the results as a plain text file. It should also be obvious when no emails were found, and the page should feel fast and easy to use.

Keep the design modern and minimal, with a clear input area, a run extract button, and a results section. Make it work well on mobile and desktop. If there is already starter code in the repo, use that and finish the product in a polished way. You can look up current docs online if you need to.
