Precision Image Compositing for Certificate

I need a strict image compositing edit, not design work and not AI generation. You will be provided with a base certificate image, a replacement badge PNG, and a signature file. Your task is to edit the original certificate directly, preserving the layout, spacing, alignment, fonts, colours, and overall structure exactly as they are. Replace all instances of “WorktoGive” with “CSR Complete”, update the central banner text to “CSR Complete Accredited – LEVEL 1”, and change the footer to “Verified at: csrcomplete.co.uk”. Completely remove the name, job title, and any reference to WorktoGive in the signature area, then insert the supplied signature and place the text “Authorised by CSR Complete” beneath it. Remove the existing badge and insert the supplied badge PNG in the exact same position and scale, preserving its transparency with no background box, no colour changes, and no visual alterations. The badge must remain pixel-identical to the source PNG, and the certificate colours must remain unchanged. This must be completed in Photoshop, Photopea, or equivalent using proper layers, not recreated or generated. Final output must be high-resolution, print quality, sharp, and indistinguishable from the original apart from the specified edits.
