PDF Text Replacement in Photoshop

I need the existing text in a PDF updated directly in Photoshop while keeping every other design element untouched. The job is purely textual—no image adjustments or layout redesigns. I will supply the PDF and a list of the exact replacement text for each section; you’ll swap the old wording for the new, matching fonts, sizes, kerning, and alignment so the final file looks identical to the original aside from the revised copy.

Please work in Adobe Photoshop, preserve layers where possible, and return both the updated, print-ready PDF and the layered PSD for my records.
