Birthday Invite Text Overlay

I have a single-page birthday invitation that Google Gemini generated for me. The artwork is saved as a PNG image file and looks exactly the way I want—except it’s missing the actual party details.

Here’s what I need:
• Add the date and time of the party, the location, and RSVP details directly onto the PNG.
• Apply tasteful text decorations or effects so the added information blends naturally with the existing style.

I’m aiming for a quick, budget-friendly turnaround. A simple edit in Photoshop, Illustrator, Canva, or any tool you prefer is fine as long as the final invitation is ready for me to email out. Please keep the original resolution intact and return the updated file as both a high-quality PNG and a PDF so guests can view it easily on any device.
