ilkerzg/storycast ? reverse-engineered prompt

Build me a web app called Storycast where someone can type in a topic and get back a short narrated animated film.

The app should let the user pick a character, a visual style, a voice, a language, and a length, then generate a polished story with a script, key scenes, animated shots, narration, music, an end card, and subtitles. It should all happen in the browser using the user’s own fal key.

I’d like a clean home page, a creation flow, and a finished film page where people can watch, share, and download the result. Make it feel fun and easy, like you can invent your own character or use one of the built in ones. If sharing needs extra setup, keep it optional and hidden unless it’s available.

Please make it work end to end and use current docs online if you need to.
