Sidddevz/Wittyr ? reverse-engineered prompt

Build me a Reddit profile roaster app that lets someone type in a Reddit username and then gets their public comment history, analyzes it, and turns it into a funny personalized roast. I want the experience to feel like a playful chat, with typing effects, a few yes or no questions, and a dramatic reveal at the end that shows the roast plus a breakdown of strengths, weaknesses, love life, and life purpose.

Make it work well on mobile and desktop, and add a language switcher so the whole app can be used in different languages without reloading. If Reddit data is unavailable, use a fallback source so it still works. I also want the app to save results and load them again later instead of redoing everything every time. Please keep the UI modern, smooth, and a little over the top in a fun way. If you need current docs for any API or library, look them up online first.
