# Downloads simulator-server (argent variant) for every supported host platform
# into platform-keyed subdirectories of packages/native-devtools-ios/bin/ — the
# layout packages/argent/scripts/bundle-tools.cjs and the runtime resolver in
# @argent/native-devtools-ios both expect.
#
# Usage: ./scripts/download-simulator-server.sh [release-tag]
#
# Requires an authenticated gh CLI: the release repo is public, but
# `gh release download` still needs auth.
