//! Vector icon set for `PackIcon` / `SymbolIcon` / `FontIcon`
//! (MaterialDesignInXaml `PackIcon`, MahApps `IconPacks`, WinUI `SymbolIcon`
//! equivalents).
//!
//! Icons are 24x24 path geometry rendered by the framework's own shape
//! engine — no icon font, so output is identical on native and wasm and
//! there is no fallback-font lottery. Subpaths rely on the WPF default
//! even-odd fill rule for holes (rings, cut-outs).
//!
//! ```xml
//! <PackIcon Kind="Home" Width="20" Height="20" Foreground="#FF444444"/>
//! ```
