Picsy is a fast, modern wallpaper application built to deliver wallpapers instantly using edge computing.

Unlike traditional wallpaper apps, Picsy leverages Cloudflare Workers to serve wallpaper content directly from the edge, ensuring minimal latency and a smooth browsing experience across platforms.

This version represents a major architectural upgrade from the initial prototype, focusing on speed, scalability, and cross-platform support.
