//! The auto-generated wisp control panel (`ui` feature): every param in the
//! shader's interface gets a widget, and load/pipeline errors appear in the
//! panel while you edit.
//!
//! Pass another shader's asset path as an argument to inspect it instead, and
//! add `--features bevy/file_watcher` for live editing.
