1//! Sheet metal: bodies of one thickness, flat faces joined by bends —
2//! brackets and enclosures — and the flat blanks they are cut from.
3//!
4//! - [`BaseFlange`] starts a body from a sketch: a plate from its area, or
5//!   a bent strip from a chain of lines and arcs, with the body's
6//!   [`SheetMetalRules`] (thickness, bend radius, K-factor, reliefs).
7//! - [`EdgeFlange`] bends a flange up from a straight edge of the body,
8//!   cutting reliefs beside it and keeping a gap at corners; [`Hem`] folds
9//!   an edge right back on itself.
10//! - [`SheetCut`] cuts holes and notches through the body, across its bends
11//!   unrolled.
12//! - [`FlatPattern`] unfolds the body: each bend laid flat as long as its
13//!   developed length, with its bend lines; [`FlatPatternDxf`] writes it
14//!   for laser cutting.
15//!
16//! Each operation records the body's [`Sheet`] for the solid it builds, in
17//! the part's target [`sheets`]: which faces are flat and which are bends,
18//! and how they join, so that the next flange and the flat pattern work
19//! from what the body is made of rather than guessing it from its
20//! geometry. The solid itself is built from the sheet in one go (see
21//! [`thicken`]).
