- Insert Goethe poem illustration (img-000.jpg) as filler page
between TOC and first song (matching reference layout)
- Remove 10 alpha mask/tiny artifact images
The remaining ~65 unused images are mostly on song pages where
CL number matching failed — they need manual assignment.

Extract images from the CL6 PDF using pdfimages, map them to songs
via page-to-CL number matching, and insert \songimage commands.
Add insert-images.py script for repeatable extraction.
