-## Caveats
-
-**Mixed image formats.** 197 of the 1,500 images carry a `.png` extension
-but their actual byte stream is WebP (171), GIF (23), or BMP (3). They
-render correctly in PIL / browsers, but services that validate the magic
-bytes (AWS Textract, Azure Document Intelligence) will reject them
-without a transcode step. Re-encoding to true PNG with dimensions
-preserved is a lossless one-liner.

 ## License
 
 Annotations: CC-BY-4.0. Page images carry their original per-source
