#    SVP_VERSION      — release to install (default: latest)
#    SVP_INSTALL_DIR  — where to drop the binary (default: /usr/local/bin)
#
#  what it does:
#    1. Detects your OS + arch
#    2. Downloads the matching binary from https://softinel.com/get/dl/
#    3. Installs it (with sudo only if needed)
#    4. Prints the version so you can confirm
#
#  supported: linux/amd64, linux/arm64, darwin/amd64, darwin/arm64
