//! Module: config::schema::component_group_deployment
//!
//! Responsibility: define strict checked-in Component Group deployment declarations.
//! Does not own: root selection, planning, or runtime state.
//! Boundary: source declarations select one group and freeze placement plus member-limit envelopes.
