+/// Defines the protocol for an output channel that can be initialized and used to send messages.
+///
+/// Implementors of this trait provide the underlying mechanism for message delivery,
+/// such as writing to stdout, a file, or a network socket.
+///
+/// # Type Parameters
+///
+/// The trait methods return `impl Future<Output = ()> + Send + Sync`, allowing
+/// asynchronous implementations that can be shared across threads.
+pub trait OutputProtocol {
+    /// Initializes the output channel.
+    ///
+    /// This method consumes `self`, indicating it should be called once during setup
+    /// to prepare the output resource (e.g., opening a file, establishing a connection).
+    ///
+    /// # Returns
+    ///
+    /// A future that resolves when initialization is complete.

+    /// across multiple concurrent senders (e.g., in multi-threaded or async contexts).
+    ///
+    /// # Arguments
+    ///
