+✅ Refactor Plan for Markdown Anchor Linking
+
+🧠 1. Understand the Problem
+
+[link](#heading) links rely on corresponding HTML elements having id="heading".
+
+marked.js by default doesn’t add id attributes to headings unless configured.
+
+Your headings might be missing ids or may not match the expected format (e.g., space vs. hyphen mismatch).
+
+
+
+---
+
+🧱 2. Refactor Outline
+
+🔧 Step 1: Customize Marked Renderer
+
+Use a custom Renderer in marked.js to automatically generate slugified ids for headings:
+
+import { marked } from "marked";
+import slugify from "slugify";
+
+const renderer = new marked.Renderer();
+
+renderer.heading = (text, level) => {
+  const slug = slugify(text, { lower: true, strict: true });
+    return `<h${level} id="${slug}">${text}</h${level}>`;
+    };
+
+    marked.setOptions({ renderer });
+
+    > ✅ You can use slugify or write your own slug generator if needed.
+
+
+
+
+    ---
+
+    🧩 Step 2: Normalize Anchor Links in Markdown
+
+    Ensure links like [My Paragraph](#my-paragraph) are slugified the same way as the ids:
+
+    Ensure slugify rules match exactly with those used in the heading renderer.
+
+    If links are auto-generated or user-written, you may want to validate or transform them in your rendering pipeline.
+
+
+
+    ---
+
+    🧪 Step 3: Test Scroll Behavior
+
+    If scrolling doesn't work as expected, make sure your links are:
+
+    Properly rendered as <a href="#some-id">...</a>
+
+    The target heading exists in the DOM at time of click (no lazy-loading issues).
+
+
+    Check for any custom scroll behavior in your layout that may interfere (e.g., smooth scroll or offset handling for sticky headers).
+
+
+
+    ---
+
+    💡 Optional Improvements
+
+    ➕ Add Smooth Scrolling
+
+    In _app.tsx or layout file:
+
+    html {
+      scroll-behavior: smooth;
+      }
+
+      🛑 Handle Scroll Offset (if using fixed/sticky headers)
+
+      Add a little scroll offset with a custom scroll handler:
+
+      useEffect(() => {
+        const handler = (e: any) => {
+            if (e.target.hash) {
+                  e.preventDefault();
+                        const id = e.target.hash.slice(1);
+                              const element = document.getElementById(id);
+                                    if (element) {
+                                            const yOffset = -80; // adjust if you have a sticky header
+                                                    const y = element.getBoundingClientRect().top + window.pageYOffset + yOffset;
+                                                            window.scrollTo({ top: y, behavior: 'smooth' });
+                                                                  }
+                                                                      }
+                                                                        };
+
+                                                                          document.querySelectorAll('a[href^="#"]').forEach((el) =>
+                                                                              el.addEventListener('click', handler)
+                                                                                );
+
+                                                                                  return () => {
+                                                                                      document.querySelectorAll('a[href^="#"]').forEach((el) =>
