/**
 * The Print button must follow what the file is, not what it is called (#2993).
 *
 * A plate exported from Studio, or a print dispatched through the cloud, is a
 * fully sliced 3MF named `Foo.3mf`. Deciding from the extension hid the Print
 * button on files the backend was perfectly willing to print -- `library.py`
 * has always accepted either type on the G-code path.
