samfoundsus/WALLPPR ? reverse-engineered prompt

Build me a premium wallpaper generator web app where people can create clean, stylish, procedural wallpapers and export them easily.

I want a polished interface with 10 different generative styles, like hills, waves, arcs, blobs, rings, mesh, contour, orbit, cells, and stripes. Let users pick a seed so they can recreate the same design later, switch between light and dark looks, choose from a few curated color palettes, and tweak the wallpaper size and composition a bit. There should also be a randomize button and a regenerate button so people can quickly explore new results.

Make it fully client side, responsive, and high quality. The wallpaper should render on canvas, and users should be able to download PNG, JPG, and a 4x export version. Use React, TypeScript, Vite, and Tailwind, and keep the UI feeling premium, simple, and easy to use. If you need to look up current docs online, go ahead.
