romm_cli/tui/
mod.rs

1//! Terminal UI module.
2//!
3//! This module contains all ratatui / crossterm code and is responsible
4//! purely for presentation and interaction. It talks to the rest of the
5//! application through:
6//! - `RommClient` (HTTP / data access),
7//! - `core::cache::RomCache` (disk-backed ROM cache), and
8//! - `core::download::DownloadManager` (background ROM downloads).
9//!
10//! Keeping those \"service\" types UI-agnostic makes it easy to add other
11//! frontends (e.g. a GUI) reusing the same core logic.
