ADDITIONAL LICENSING INFORMATION:

This product includes software developed by Scott Wheeler and the TagLib 
contributors (https://taglib.org/).

The WebAssembly binaries (build/taglib-web.wasm for the Emscripten backend
and build/taglib-wasi.wasm for the WASI backend, shipped as dist/*.wasm)
contain compiled TagLib code which is licensed under LGPL-2.1-or-later.
The original TagLib source code is located in lib/taglib/. See
lib/taglib/COPYING.LGPL for the full LGPL license terms.

LGPL COMPLIANCE:
The WebAssembly binaries are subject to LGPL requirements. This means:
- You may use them in commercial applications
- Modifications to TagLib must be shared under LGPL
- You must enable users to relink with modified TagLib versions

To rebuild the WebAssembly binaries with a modified TagLib:
1. Modify the TagLib source in lib/taglib/
2. Run: npm run build:wasm  (builds both backends; requires the
   Emscripten SDK and WASI SDK 33 — see CONTRIBUTING.md)
3. The new binaries will be in build/taglib-web.wasm and
   build/taglib-wasi.wasm
