## TL;DR

The Clipboard API provides asynchronous browser access to clipboard read and write operations, subject to security and permission constraints. The repaired version avoids overbroad format and gesture claims.

## Core Explanation

The modern web clipboard surface centers on Navigator.clipboard and Promise-based methods. The W3C specification defines clipboard events and ClipboardItem, while MDN emphasizes that access is restricted to secure contexts and browser permission/security controls.
