Namespace LMKit.Document.Annotations.Pdf

PdfAppearanceStream: Renders a built annotation appearance (AppearanceElements) into a PDF appearance-stream: the content operators plus the resource requirements (transparency graphics states, fonts) the hosting form must declare. This is the PDF leg of the standard's appearance engine - the geometry is already final (rotation baked in by the builder); this class only changes coordinate conventions (top-left → bottom-left) and speaks the operator syntax.

PdfGraphicsStateResource: A transparency graphics-state resource an appearance form must declare.
