PinnaPetta corresponding third-party sources

The media archives and build script correspond to the separate FFmpeg, ffprobe,
and webpmux executables. This includes dav1d 1.5.4 (BSD-2-Clause) for AV1 decoding.

Downloader sources include the exact yt-dlp release, its upstream build recipes,
QuickJS-NG, and the pinned Python dependency sources, including Mutagen (GPL)
and certifi (MPL). The macOS executable is the unmodified official Universal
standalone distribution except for framework symlink normalization and Developer
ID signing, both documented in the included build and embed scripts. The source
manifest records the hashes and original download URLs. Refer to the upstream
build recipes and dependency licenses for rebuilding these components.

No application license limits the rights granted by these third-party licenses.
These source archives accompany the matching binary at pinnapetta.com/download.
