+  support keyboard movement and precise percentage-coordinate entry
 - Rotate in quarter turns, adjust deskew manually, or estimate a text-line
   correction within ±5 degrees
 - Tune brightness and contrast, retain colour, convert to grayscale, or create
   black-and-white pages using Otsu or a manual threshold
 - Preserve the previous preview until its debounced replacement is ready
+- Run perspective correction, pixel adjustment, rotation and deskew analysis in

 This first release does not automatically detect page corners, remove fingers
 or shadows, process input PDFs, recognize handwriting reliably, or create a
-searchable invisible PDF text layer. OCR confidence is engine evidence, not an
+searchable invisible PDF text layer. Geometry is exported separately so an
+unverified alignment is never embedded into the PDF. OCR confidence is engine evidence, not an
 accuracy guarantee. Perspective correction is high-quality bilinear resampling;
 each new render is lossy unless exported as PNG.
