Edición perfecta de documentos escaneados

Edit this scanned document. Remove the lower duplicate signature and stamp at the bottom, leaving only the upper signature and stamp. Keep the text "Instituição de ensino" exactly as it appears. Replace the word "cidade" immediately before the date with "Santana de Parnaíba". Keep all other text, layout, formatting, ink, and document details completely unchanged. The edits should blend seamlessly with the original scanned document.
