+/// A drop-in replacement for `tauri_specta::collect_commands!` that supports
+/// `#[cfg(...)]` attributes on individual commands.
+///
+/// # Example
+/// ```rust
+/// collect_commands![
+///     #[cfg(desktop)]
+///     desktop_tray::set_close_to_tray_enabled,
+///     windows::snap_overlay::show_snap_overlay,
+///     windows::snap_overlay::hide_snap_overlay,
+/// ]
+/// ```
+///
+/// # How it works
+///
+/// For each unique cfg predicate P found in the list the macro generates two
+/// complete `tauri_specta::internal::command(generate_handler![...],
+/// collect_functions![...])` calls — one for `#[cfg(P)]` (including those
+/// commands) and one for `#[cfg(not(P))]` (excluding them).  The compiler
+/// picks exactly one branch per target, so every command path only needs to
+/// exist on the targets where its cfg condition is true.
+///
+/// For N distinct predicates, 2^N branches are emitted.  In practice only
+/// `#[cfg(desktop)]` is used so this is always just two branches.
