facett-model3d/examples/skull_demo.rs

//! `cargo run -p facett-model3d --example skull_demo`
//!
//! A spinning skull whose eyes fade green→yellow→red as you drag the **status**
//! slider. Drag the model to rotate it by hand (pauses the auto-spin).
//!
//! Pure egui on the **glow** backend (no wgpu / no custom shader).
