// The NON-visible 2-flat-hop author: a two-field generic `Box` (size 16) with its
// own `make` (sets a second field). Same template NAME as b's, different layout.
// It wins the global last-wins `struct_template_map` (and the name-keyed
// `Box.make`), so the static-method head in a file importing only b.sx must NOT
// pick it.
