## What this plugin does

Neo Library provides a modular framework of gameplay, utility, UI, AI, ability, animation, online, and replication helpers for Unreal Engine:

* Use module-specific Blueprint/C++ APIs instead of reinventing common systems.
* Reuse standardized helpers for graphics, input, traces, randomization, scalability, debugging, and OS/platform queries.
* Control Iris replication priority, filtering, and update behavior through Blueprint-friendly runtime helpers.
* Integrate ability/AI/UI/online workflows with consistent conventions.

In simple terms: less utility boilerplate, more production-ready building blocks.
