1/// Component method call demo.
2///
3/// Loads component-method-call.mms, which authors the scene and wires signal
4/// handlers that call `anim.pause()` and `anim.play()` on a live AnimationComponent.

6/// Click the blue cube  → pause the spinning animation.
7/// Click the green cube → resume the spinning animation.
8///
9/// Run: cargo run --release --example component-method-call
