section where the BOOK APPEARS, not where it was first downloaded:
- CW9/I: 7 files moved sec02/sec04 -> sec01 #04 (sec02+sec04 now cross-ref sec01)
- Red Book: 4 files moved sec04 -> sec01 #35 (sec04 #03 cross-refs sec01)
- #34 'Undiscovered Self': file was never lost — always in sec01; removed the
misleading line from the 'Cross-refs EN' block (per-item #34 lists it)
- audit: all 14 duplicate groups now have files in their canonical (earliest)
section; totals: sec01 113 / sec02 37 / sec04 28
- cards: sec01/04 + sec01/35 get Downloads tables; sec02/04, sec04/01, sec04/03
Downloads -> cross-ref sec01
