//! Run the real `jepa train` image-folder path against a tiny generated dataset.
//!
//! This example creates a recursive dataset directory with a handful of PNG
//! files under `target/example-data/jepa/demo-image-folder`, then feeds that
//! directory into the same strict training command used by the CLI.
//!
//! Run with:
//!
//! ```bash
//! cargo run -p jepa --example train_image_folder_demo
//! ```
