What problem does it solve?

Design challenges arise when representing heterogeneous world objects without inheritance. A flat, uniform Entity layout paired with ZII memory patterns reduces code-path branching, simplifies debugging, and improves memory locality.

Core Features & Use Cases

• Uniform memory footprint: every Entity shares the same layout, enabling predictable iteration and straightforward packing/unpacking.
• Feature composition via property bitflags: combine behaviors without per-type polymorphism.
• ZII-driven defaults and arena-based memory: zero-initialized memory means entities start in a safe, inert state and arenas provide efficient lifetime management.

Quick Start

Create a minimal flat Entity using a zero-initialized arena and demonstrate property flags to compose behaviors.
