 A modern web and mobile application for ZoneMinder, providing a clean, intuitive interface for viewing live camera feeds, reviewing events, and managing multiple server profiles. It is a ground-up rewrite of the original [zmNinja](https://zmninja.zoneminder.com/) application, using modern web technologies and a more intuitive user interface. The code was 99% Claude CLI generated.
