//! 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, 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").
