README Excerpt

<div align="center"> <img src="./assets/hero.png" alt="Umbriel" width="100%" /> Drive any Windows app through five layers — fall back to OCR and pixel-matching when there's no other way in, see and manage windows even when they're hidden, send cursor-free synthetic input, target controls by name and role, and reach past the GUI to drive the OS itself: processes, services, the registry, scheduled tasks, the firewall, network, power, displays, disks, environment, and the event log.
