//! The "CAM" workbench — Fusion 360's Manufacture workspace and SOLIDWORKS
//! CAM in this app: setups, tools and operations that machine the modelled
//! part, generated into toolpaths and posted to NC programs.
//!
//! CAM 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 a setup machines is the model the
//! history already built. What the workbench adds is its CAM pane — the
//! browser tree of Setups › Operations, NC Programs and the Tool Library —
//! and the four toolbar buttons below, each of which surfaces the pane and
//! hands the pane its action.
//!
//! Everything CAM makes lives in the document's own `cam` block, never in the
//! history: user inputs (setups, tools, operations, post settings, target
//! references) are saved; toolpaths, meshes, indexes and stock states are
//! derived and regenerated.
