//! The "Assembly" workbench — assemblies build-spec §8.1.
//!
//! Creatable set: the shared building blocks (sketch `S` / datum `D` / plane
//! `P`) plus the ASSEMBLY COMPONENT (`ACOMP`) — in-context sketches on
//! component faces are an allowed reference use (spec §3), so S/D/P stay
//! creatable here. Everything else (modeling + sheet metal) is filtered out of
//! the creation UI; the history itself stays fully visible/editable regardless
//! of workbench (standing rule).
//!
//! Claims the two assembly panels (Assembly Structure tree + Assembly
//! Constraints), which therefore show ONLY under Assembly (and "All").
