1//! Custom Theme Example — FlashKraft GUI
2//!
3//! Launches the FlashKraft desktop application with a pre-selected theme,
4//! demonstrating the full theme system:
5//!
6//! - 21 built-in Iced themes (dark + light variants)
7//! - Runtime theme switching via the 🎨 button
8//! - Theme preference persisted across sessions via `sled`
9//! - Every UI component — buttons, progress bars, panels — adapts instantly
10//!
11//! # Run
12//!
13//! ```bash
14//! cargo run -p flashkraft-gui --example custom_theme
15//! ```
