Primary sources are the rembg repository, LICENSE.txt, README installation section, and GitHub Releases asset lists. Secondary sources are PyPI package metadata for rembg.
Invented winget or Homebrew ids are out of scope for this guide. When a package manager path is missing, the guide says so and keeps Windows on Releases exe files or macOS/Linux on pip.
Installer UI wording on real Windows machines may remain unverified on the Linux build box; asset names are still confirmed against the live release API. Re-verify on the date shown in the stamp.
