Bala0o8o0/lumina-tryon ? reverse-engineered prompt

Build me a polished virtual try on web app where people can sign up, buy credits, upload a photo of themselves and an outfit, then get an AI generated image of how the outfit would look on them.

I want it to feel premium and modern, with a strong landing page, smooth animations, and a mobile friendly experience. The app should use user accounts, keep track of credits, and only let people generate when they have enough balance. Please make the credit flow safe so credits are taken before the try on starts, and add a simple payment flow for topping up credits.

If the AI generation service is unavailable or runs out of quota, the app should still work by showing a believable demo result instead of failing. Use the current best practices for auth, payments, and image handling, and look up current docs online if you need to.
