The small CloudMP3 bridge and wrappers invoke separately replaceable LGPL shared
libraries. Corresponding source archives are present in downloads/, complete
extracted sources in vendor/, and exact build instructions in rebuild.sh.
Users may rebuild/relink these libraries, including modified versions, for
their own use and for debugging modifications permitted by the LGPL.

Release packaging: retain this notice and the license files in the app. Make
the exact source archives, cloud_mp3.c/.h and rebuild.sh available alongside
the binary release (or bundle them); official upstream URLs alone are not the
complete corresponding-source distribution for this exact build. Do not claim
Developer ID signing/notarization from the included local ad-hoc signature.
