//! Attachment badge suffix for the input area title.
//!
//! [`attachment_suffix`] produces a short string like `| 📷 2 attached | 🧭 1 queued`
//! reflecting pending images and steering messages.

use crate::tui::app::state::App;

/// Build a short suffix like `| 📷 2 attached | 🧭 1 queued` or empty.
///
/// Returns an empty `String` when there are no pending images or steering
/// messages, so the input title stays clean.
///
/// # Examples
///
/// ```rust,no_run
/// use codetether_agent::tui::ui::chat_view::attachment::attachment_suffix;
/// # fn demo(app: &codetether_agent::tui::app::state::App) {
/// // With no attachments the suffix is empty.
/// let suffix = attachment_suffix(app);
/// assert!(suffix.is_empty() || suffix.contains("📷"));
/// # }
/// ```
