This file is added under content/blog-post-2026-07-12/, but the site content collection only loads MDX files from content/blog/**/*.mdx. The post will be skipped by the generated posts data, so it will not appear on the blog index, route generation, sitemap, or RSS feed.

Add 'use client' to this example.
onClick makes this a Client Component; without the directive, copying it into an App Router page.tsx will fail unless it’s moved into a client child component.
