Bevy project foundations

When to use

Load this when a new Bevy app needs a crate, a pin, and a place for feature code before gameplay systems exist. Folder names below are layout habits. They are not engine types.

ECS shape

• Crate: cargo new plus a bevy dependency pinned at 0.20.
• Features: default pulls windowing, input, and rendering. Turn default-features off only when the binary should stay headless.
• App shell: App::new(), plugins, then systems and resources on that App.
• Code layout: Split by feature in ordinary Rust modules. The engine does not require a directory tree.

Pin the crate and keep dev builds usable. Bevy's default debug profile compiles dependencies unoptimized, so the dev profile lifts dependency opt-level while the game crate stays easy to step through.
