# AimHuge Workshops — macOS machine setup
# ----------------------------------------
# Takes a stock Mac to a working dev stack:
#   Homebrew · Node (LTS) · pnpm · Claude Code · Vercel CLI · Supabase CLI · Superwhisper
#
# Run with:  bash <(curl -fsSL https://aimhuge.com/setup/mac.sh)
# Idempotent and safe to re-run if a step fails.
#
# Supabase is set up for the HOSTED workflow (CLI for migrations + type-gen).
# No Docker is installed. Resend needs no install — it's an npm package + API key.
