2# setup-scc.sh — install scc (github.com/boyter/scc), used by
3# scripts/garry-output-comparison.ts for logical-line classification of added lines.
4#
5# Why standalone (not a package.json dependency): 95% of gstack users never run
6# the throughput script. Making scc a required install step for every `bun install`
7# would bloat onboarding for no reason. This script is invoked only when you
8# actually want to run garry-output-comparison.ts.
9#
10# Usage: bash scripts/setup-scc.sh
