//! The instance-lockout **Era surface** (decision 1748): the three engine bindings, and the one
//! place in the shipped UI that reads them — the SELF menu's "Reset all instances" row and the
//! `CONFIRM_RESET_INSTANCES` dialog behind it.
//!
//! The four chat lines the family's other packets raise are engine-composed and have no Lua at
//! all (no FrameXML file mentions `RAID_INSTANCE_WELCOME` or its siblings); they are tested at the
//! composer, in `crate::ui_instance`.
