bevy-react 0.1.0

//! Headless checks for the animations engine wiring: it's on by default and can
//! be opted out with `.with_animations(false)`. We only inspect resources after
//! the plugin builds (no `app.update()`), so no GPU/window is needed.

/// bundle, so we create both. Classic scripts (no ES-module syntax), since the
/// runtime runs them via `execute_script`. Unique per test to avoid races.
