//! The "PMI" (Product & Manufacturing Information) workbench — the mode in
//! which PMI views are captured and annotated.
//!
//! PMI is NOT feature creation: the `includes` predicate rejects every
//! catalogue entry (the Add-feature palette is empty here), and the history
//! stays fully editable as everywhere. What the workbench adds is its PMI
//! panel — the view tree with each view's annotations — the **Capture view**
//! button, the actions strip's **Annotations** group, and the context bar's
//! annotation offers (gated on an active view). The workbench
//! IS the editing mode: entering it remembers the modeling camera / visibility
//! / wireframe, activating a view applies that view's, and leaving restores
//! them (`app.rs` drives the engine's `pmi_enter_workbench` /
//! `pmi_leave_workbench` off the panel's visibility).
//!
//! Drawing sheets — which PLACE the views captured here — are the Drawing
//! workbench's (`workbench/drawing.rs`), not this one's.
//!
//! The one-button-per-annotation-type group is NOT here: like the Constraints
//! group, it is derived from the kernel's table and lives on the workbench
//! actions strip (`panels/workbench_toolbar.rs`), shown wherever this panel is.
