PDF.js is licensed under Apache-2.0; see 6.3.289-app1/LICENSE and the bundled font/WASM notices.
The 6.3.289-app1 directory omits source maps and the sample PDF. Upstream JavaScript is unchanged. web/viewer.html selects German, restricts connections to the same origin, and loads /assets/pdf-viewer.js and /assets/pdf-viewer.css for application configuration and styling. The application disables document scripting and editing, and routes downloads through its original-file endpoint. All runtime assets are served locally. The directory suffix is a cache revision; increment it when changing bundled files.
