# Officer — macOS laptop setup.
#
# The barebones counterpart to scripts/setup/setup.sh (which targets an Ubuntu/Debian server and is left
# alone). This installs only what a laptop workflow needs: the file browser, Claude/opencode chat,
# and a terminal. No Go/Rust/cliamp/PulseAudio, no neovim, no shell dotfile stack, no VNC desktop,
# no sudoers grant, no power-management changes.
#
# EVERY STEP IS OPTIONAL. Each one prompts before doing anything, and can be preset non-interactively:
#
#   SETUP_POSTGRES=0 SETUP_OPENCODE=0 bash scripts/setup/setup_mac_light.sh
#
#   SETUP_PACKAGES   brew node@22 / bun / ffmpeg          SETUP_CLAUDE     claude code CLI
#   SETUP_POSTGRES   brew postgresql@18 + createdb        SETUP_OPENCODE   opencode CLI
#   SETUP_LINK_NODE  brew link --force node@22            SETUP_DEPS       bun install
#   SETUP_PM2        pm2 via npm                          SETUP_ENV        write .env
#   SETUP_INIT       gen:index + db:push                  SETUP_SERVICES   pm2 startOrRestart
#
# Accepted values: 1/y/yes/true to run, anything else to skip. Unset = ask (or take the default when
# stdin is not a terminal).
#
# This script never calls sudo itself — everything lands under the Homebrew prefix or $HOME. Note
# that Homebrew's own installer does ask for an administrator password on a fresh Mac.
#
# Usage: bash scripts/setup/setup_mac_light.sh
