Photo Text Stamp Editing

I have a single phone screenshot that already contains stamped text. I need that text replaced—not removed, not added elsewhere—while preserving the exact look and placement of the original font, colour, size, and alignment. The wording itself must change; I’ll supply the current copy plus guidance on how I’d like it paraphrased so the meaning shifts slightly but remains clear.

Please work non-destructively (layered PSD, Affinity, or similar) so I can come back for tweaks if the phrasing needs another adjustment. Final deliverable should be the edited high-resolution image in PNG or JPG along with the layered source file. Accuracy in matching the original style is the priority; once it passes a side-by-side review I’ll release full approval.
