- Services/PdfRedactText.cs: strip text whose origin falls inside a CoverAnnotation from the page content stream at save time, hooked into PdfBurn.DrawAnnotationsIntoDoc. Fixes edited values staying recoverable by text extraction. - Themes/MMD.xaml replaces all thirteen themes; picker and accent strip removed; no dark mode. - Rename KillerPDF -> MMD PDF across code, resources, packaging and locale strings; new icon. - Remove the upstream author credit and the in-app install button.
