28/// A sheet-metal mounting bracket: a 2 x 1.2 plate 0.08 thick (`plate`),
29/// a flange bent up along part of its front edge with reliefs beside it
30/// (`front`), one along all of its back edge (`back`), and two mounting
31/// holes cut through the plate after flanging (`mount`, drawn in `holes`)
32/// — the body is `sheet_cut(mount)`.
