## About

Brim is a lightweight tool that lets web pages take advantage of the iPhone Duo's outer display in Safari. It bridges the gap between the dual‑screen hardware and web content, giving developers a larger canvas without native app development. By enabling full‑screen rendering on the outer display, Brim expands the web experience for Duo users. The solution is simple: it modifies Safari's rendering path to expose the outer screen to web pages.
