Bevy adapt 3D to 2D

When to use

Load this when a 3D design should render as sprites or billboards. Gameplay components stay. Render components change.

ECS shape

• Draw: replace mesh and PBR material entities' render parts with Sprite where a billboard is enough.
• Camera: use Camera2d from bevy-camera-systems.
• Lights: 3D light entities are not required for an unlit sprite. Do not leave clustered-light assumptions in gameplay code.
