All Open Graph tags missing — link previews render as blank tiles

Open Graph tags are short lines of code in a webpage's header that tell platforms like LinkedIn, Slack, and iMessage what title, description, and image to show when someone shares your URL. Without them, your link appears as a plain, unbranded box when shared — dramatically reducing click-through and making your business look less professional. Add og:title, og:description, and og:image meta tags to every page, and verify the result using LinkedIn's Post Inspector or Facebook's Sharing Debugger.
