/**
 * A sliced 3MF named as a project must still offer Print (#2993).
 *
 * Download an archive that carries the green GCODE badge, re-import it, and the
 * file came back without a Print button. Nothing was lost from the file -- the
 * download serves the stored bytes verbatim -- but the library decided what it
 * was from the filename, and a per-plate export or a cloud-dispatched print
 * arrives as `Foo.3mf` with its G-code intact.
 *
 * The backend has always been willing to print these (`library.py` takes both
 * `3mf` and `gcode.3mf` on the G-code path), so this was the UI refusing to
 * offer something that would have worked.
