   周間 Zhoujian — a thread-bound book (線裝書).
   The cover (indigo cloth, stitched spine, title slip) is where you cast.
   The pages (moon-white paper) are where you read. The original text is
   set like a woodblock page. Cinnabar marks change and annotation only:
   changing lines, the circled focus line, AI commentary.
