+Add a menu entry in `hugo.toml` with `params.external = true`:
+
+```toml
+[[menus.main]]
+  name = "GitHub"
+  url = "https://github.com/youruser"
+  weight = 10
+  [menus.main.params]
+    external = true
+```
+
+- `name` is used as-is (not looked up in i18n)
+- `url` must be a full URL including scheme
+- `weight` controls order relative to other menu items
+- External links open in a new tab with `rel="noopener noreferrer"` and include a screen-reader-only "(opens in new tab)" label for WCAG 2.1 AA compliance
