Currently, the recommended way to run Servo as a browser is via servoshell, our winit and egui-based requires the following: 1. The OpenHarmony SDK. This is sufficient to compile servo as a shared library for OpenHarmony. 2. The hvigor build tool to compile an application into an app bundle and sign Source Code from Mirrors" and click the download link for the version of "Public SDK package for the standard system" matching your host system. 3.
