1//! The same functionality as [`basic`], but with real lucide-icons
2//! glyphs via the `icons` feature.
3//!
4//! Run with:
5//!
6//! ```sh
7//! cargo run --example with_icons --features icons -- /path/to/browse
8//! ```
9//!
10//! The only difference from `basic` is the `iced::application` call:
11//! we have to register the bundled lucide TTF with iced, otherwise the
12//! glyphs render as tofu squares. The crate re-exports
13//! [`LUCIDE_FONT_BYTES`] for exactly this purpose.
