+/**
+ * check-phone-print-keep.mjs — on a phone, the in-page print document outlives afterprint, so a saved PDF is the preview.
+ *
+ * THE DEFECT (2026-10-02, on a phone): UPG 100 → Print prayer packet. The print preview showed all 11 pages; "Save as
+ * PDF" saved the WEBSITE (one letter page with the host page's title). On a phone printDocument mounts the document into
+ * the page (#dxm-print-root plus a print-only style) and calls window.print(). It dropped both at afterprint, but
+ * Android Chrome's print() does not block, afterprint fires once the PREVIEW is built, and the saved file is rendered
+ * later, after the reader taps Save, from the page as it is then.
+ *
+ * A timeline on fake timers and a stub DOM, with an Android user agent (Playwright cannot reproduce Android's print
+ * pipeline; the Driver's phone is the real check):
+ *   A. after print() and afterprint, the document and its print style are still mounted 30 s on (the Save render);
+ *   B. it goes once the reader is BACK: the page shown again after being hidden, the window focused again after
+ *      losing focus, or a touch after print(), then BACK_GRACE_MS later, not before;
+ *   C. a late print (needs-tap): the Print tap itself does not count as being back, so the document is still
+ *      mounted through the dialog;
+ *   D. a reader who never comes back: dropped at FRAME_CEILING_MS, not before;
+ *   E. printImageBlob: its object URL is NOT revoked at afterprint, and is revoked when the document goes;
+ *   F. a new print replaces the previous document (one root mounted, and the previous one released);
+ *   G. the desktop path is the frame, as before (printDocument's first line, verbatim).
+ * `--impl=<path>` runs the timeline against another copy (the pilot's, before this fix, fails A and E: the cause).
+ * `--self-test`: the old drop at afterprint, no release when the reader is back, the listeners armed at mount (so the
+ * Print tap drops it), no grace, printImageBlob revoking at afterprint, and no ceiling must each FAIL.

A timeline on fake timers and a stub DOM with an Android user agent: still mounted 30 s after afterprint; released once the reader is back (shown again after hidden, focused again after blur, or touched after print()) plus BACK_GRACE_MS, or at the ceiling; the Print tap of a late print does not count; a new print replaces it; desktop is the frame path, verbatim. --impl=<path> runs it against another copy (the pre-fix file fails).
