Usage notes
- The method writes a /Type /Bead dictionary with /T, /P, /R, /N, and /V entries
- Multiple beads in the same thread are linked into the circular next and previous chain required by PDF readers
- The current page receives a /B bead array entry, and the thread dictionary tracks its first bead
- The active PDF version must support article threads, so HotPDF raises or validates PDF 1.1 according to StrictVersionLock
