+ * MemoView component displays a memo card with all its content, metadata, and interactive elements.

+ * Features:
+ * - Displays memo content with markdown rendering
+ * - Shows creator information and timestamps
+ * - Supports inline editing with keyboard shortcuts (e = edit, a = archive)
+ * - Handles NSFW content blurring
+ * - Image preview on click
+ * - Comments, reactions, and relations
+ *
+ * @example
+ * ```tsx
+ * <MemoView
+ *   memo={memoData}
+ *   showCreator
+ *   showVisibility
+ *   compact={false}
+ * />
