An Antora extension that checks Asciidoc source files for repeated words in prose.

The extension detects:

• image macros in Asciidoc source where there is no image file at the specified path.
• image macros that have specified sizes that differ from the image. "Retina"-resolution images are accepted (x and y are 2x visible size).
• images that exist in the Antora module hierarchy but are not referenced in Asciidoc.
