+    <!--
+    IMPORTANT: For proper social media previews, Open Graph tags must be rendered server-side.
+
+    Options:
+    1. Use a serverless function (Vercel, Netlify, Cloudflare Workers) to read query params and inject OG tags
+    2. Use a service like htmlrewriter or edge functions
+    3. Use a simple server (Node.js, PHP, etc.)
+
+    The URL format from the app is:
+    https://portfoliojournal.app/share?goal=My%20Goal&progress=42
+
+    Your server should read these params and set:
+    - og:title = "I'm 42% towards my 'My Goal' goal!"
+    - og:description = "Track your investment goals with Portfolio Journal"
+    -->
+
+    <!-- Default/Fallback Meta Tags (shown when no params or for non-social contexts) -->
