Build me a fun web app called Top 4 Theory that lets someone enter a public Letterboxd username and instantly get a “Cinema Level” score from 1 to 10 based on their favorite Top 4 films. It should feel like a polished Letterboxd inspired movie taste analyzer with a dark theme, a simple input form, and a results page that explains the score in a playful way.

Use the public profile data to inspect the four favorite films, then compare them with movie info from TMDB to judge things like rating quality, genre variety, rarity, era mix, and cinephile traits. Show the final level, a short title for that level, a breakdown of the score, and make the result easy to share. No login needed, just type a username and go. If you need current details for Letterboxd or TMDB access, look up the latest docs online.
