## Overview

LunaVerta is a static, browser-based file converter and PDF editor: users select local files, choose a tool, process documents on-device, then save the result. The graph preserves the README’s major capabilities and documented local state/offline behavior. Runtime source files were not excerpted, so capability links rely on README statements rather than claims about uninspected calls.

Main entry points: [`docs/assets/app.js`](https://github.com/midttech/lunaverta/blob/main/docs/assets/app.js) (Tool interface), [`docs/assets/editor.js`](https://github.com/midttech/lunaverta/blob/main/docs/assets/editor.js) (PDF editor), [`src/static/sw.js`](https://github.com/midttech/lunaverta/blob/main/src/static/sw.js) (Offline service worker), [`docs/assets/strings.js`](https://github.com/midttech/lunaverta/blob/main/docs/assets/strings.js) (Language strings)
