#!/bin/bash
# Print (or download) the permanent download link for the latest S4L staging
# release (.mcpb).
#
# Usage:
#   bash scripts/get-latest-staging-mcpb.sh [--download] [--channel]
#
# Options:
#   --download    Download the .mcpb to the current directory (instead of
#                 just printing the URL)
#   --channel     After downloading, opt this machine into the staging
#                 channel (delegates to scripts/s4l_channel.py, the single
#                 source of truth for the channel marker)
#
# The link below is a FIXED URL, not a live GitHub API lookup: every
# `bash scripts/release-mcpb.sh --staging` run mirrors its .mcpb onto a
# separate, non-version-tagged release ("staging-latest") so this exact URL
# always serves whatever's newest — see scripts/release-mcpb.sh step 7b. That
# means this script needs zero network calls to resolve anything; it only
# hits the network when actually downloading.
