Oracle Apex Card to upload on LinkedIn as Image and text

I already have a fully styled member-card in my Oracle APEX app—HTML and CSS are finished and display exactly as I need, showing the member’s name, photo and organisation. What I’m missing is a clean, reliable way to turn that existing markup into a high-resolution image I can post on LinkedIn alongside pre-built text.

Your task is to take the current HTML/CSS card and deliver a crisp PNG (or comparable format) optimised for LinkedIn’s feed dimensions. If you prefer working with headless browsers (Puppeteer, Playwright, wkhtmltoimage, etc.) or a lightweight CSS-to-image library, that’s fine so long as the final output remains pixel-perfect and easy for me to reproduce whenever I generate new cards.

Please keep any code or small script you create well-commented so I can reuse it inside Oracle APEX or from the command line. My priority is image quality, fidelity to the original design and a straightforward workflow.
I need Button for "Linkedin Share" which will automatically pick the image and prebuilt text and postis shared on LinkedIn.
