 ## Callouts
 
 ::alert{type="info"}
-This is an information callout.
+**Info** — Informational message. Supports **bold** and `inline code`.
 ::
 
 ::alert{type="warning"}
-This is a warning.
+**Warning** — Check Nuxt 4 compatibility before installing a module.
 ::
 
 ::alert{type="tip"}
-Practical Kotlin development tip.
+**Tip** — Use `pnpm` instead of `npm` for Nuxt projects (faster resolution).
 ::
 
 ::alert{type="danger"}
-Critical error — do not ignore.
+**Danger** — Never commit API keys or secrets in plain text.
 ::

+
+## Columns
+
+::columns{cols=2}
+  ::div
+  **Column 1**
+
+  Content of the first column. Ideal for comparing two approaches, showing before/after, or listing pros and cons.
+  ::
+
+  ::div
+  **Column 2**
+
+  Content of the second column. Columns automatically stack on mobile.
+  ::
+::
+
+::columns{cols=3 gap="lg"}
+  ::div
+  🚀 **Fast**
+
+  Nuxt SSR generates HTML server-side.
+  ::
+
+  ::div
+  🔍 **SEO**
+
+  Every page is crawlable without JavaScript.
+  ::
+
+  ::div
+  🎨 **Flexible**
+
+  Tailwind + Nuxt UI for all your styling needs.

+
+## Collapsible Content
+
+::details{summary="View full plugin implementation"}
+```kotlin

+    }
+}
+```
+::
+
+::details{summary="Why use @nuxt/content?" open=true}
+`@nuxt/content` transforms Markdown files into crawlable SSR pages. Benefits:
+
+- **Zero CMS** — articles live in the Git repo
+- **Typed** — Zod schema on every collection
+- **MDC** — Vue components inside Markdown
