## Description

**OPFS Explorer** adds a dedicated DevTools panel for browsing and managing files stored in the Origin Private File System (OPFS). Explore visual file trees, edit JSON, JavaScript, TypeScript, HTML, CSS, and Markdown files, preview images, calculate directory sizes, and perform full CRUD operations including create, rename, duplicate, move, upload, download, and delete.

Built for PWAs, SQLite Wasm applications, browser-based IDEs, and other projects using `navigator.storage.getDirectory()`, OPFS Explorer also includes multi-selection, drag and drop, storage statistics, keyboard shortcuts, configurable JSON formatting, theme support, and WCAG 2.1 AA accessibility. It runs locally without host permissions, content scripts, telemetry, or external connections, using only minimal clipboard access for copying paths.
