+//! Account layer — the ircd's *services-ready* account support, modelled on
+//! InspIRCd's `m_services_account`. **This is NOT a services daemon.**
+//!
+//! echoIRCd stores no passwords and runs no NickServ — registering nicks/channels
+//! is a **services package**'s job (Anope/Atheme), linked in over S2S. What the
+//! ircd owns is only the plumbing a service plugs into:
+//!   * a per-user **account name** (`User.account`) — the extension a service sets
+//!     or clears (InspIRCd's `accountname` metadata), which flips user mode `+r`;
+//!   * the account-gated **modes** (chan `+R`/`+M`, user `+r`/`+R`) that key off it
+//!     and live in [`crate::mode`];
+//!   * the **interface** a service drives it through: [`Server::set_login`] /
+//!     [`Server::logout`], reached today via the oper/`SVSLOGIN` command and, once
+//!     S2S + SASL land, by a linked services pseudoserver.
+//!
+//! So a real network runs Anope *beside* echoIRCd; the ircd just has to be ready.
