## Overview

This is a small Bevy ECS demo: startup creates four people, then chained systems query their components and print names and employment reports. Person, Employed, and Job define the domain data. The graph reflects the only sampled source file; no README documents additional capabilities.

Main entry points: [`src/main.rs`](https://github.com/issarat/rust-bevy/blob/main/src/main.rs) (App entry)
