# Usage:
# ./install-ls.sh # auto: our release → Exafunction fallback
# ./install-ls.sh /path/to/local.bin # install a local file
# ./install-ls.sh --file /path/to.bin # same as above
# ./install-ls.sh --url <direct-url> # install from a custom URL
#
# Auto-detects platform (Linux / macOS) and architecture (x64 / arm64).
# Override install path with LS_INSTALL_PATH env var.
