Concepts

I removed the navigation links (previous/next, breadcrumbs) because they’re not part of the main content.

I don’t see any actual page content to convert into GitBook-optimized Markdown. Please paste the page body you want converted (headings, paragraphs, code, lists, images, etc.), and I’ll transform it per the guidelines (convert package-manager blocks to tabs, turn long numbered lists into steppers, convert FAQ to expandables, etc.).
