/**
 * Primary content container surface.
 *
 * @description
 * Groups related content visually by applying background (`bg-card`),
 * rounded corners, and structured internal padding via sub-components.
 *
 * @ai-rules
 * 1. NEVER create raw divs with `bg-white dark:bg-black rounded border shadow` — use `<Card>`.
 * 2. Compose with the semantic order: `CardHeader > CardTitle + CardDescription > CardContent > CardFooter`.
 * 3. For inline action buttons in the header, use `<CardAction>` (rendered right-aligned automatically).
