//! **NavModel → facett-menu bridge.** Now that `facett_menu::Command` takes owned
//! ids, the *same* [`NavModel`](crate::NavModel) that drives the sidebar and
//! breadcrumb can also drive facett-menu's palette, menubar and context-menu —
//! "one model → many surfaces" all the way through. Each navigable leaf becomes a
//! [`Command`](facett_menu::Command) whose `id` is the route and whose `group` is
//! the parent section's label.

use crate::nav::{NavItem, NavModel};
use facett_menu::Command;

/// Build a facett-menu command set from a nav model: one command per enabled leaf
/// (`id` = route, `group` = parent section label, else `"Go"`), icons preserved.
