-//! rustbot — a small, modular IRC bot, split into a reusable library (this
-//! crate) and a thin binary (`src/main.rs`).
-//!
-//! Modules:
-//!   * [`irc`]    — protocol + transport (the "IRC library"): message parsing,
-//!                  IRCv3 tags, and a blocking TCP/TLS [`irc::Connection`].
-//!   * [`bot`]    — behavior: registration, capability negotiation, the event
-//!                  loop, and commands, driving one [`irc::Connection`].
-//!   * [`config`] — the layered [`config::Config`] and how it is loaded from a
-//!                  file (with optional `[network]` sections) and environment.
-//!
-//! The binary adds only a per-network connect/reconnect supervisor on top, so
-//! the whole bot is exercisable — and reusable — through this library's API.
