# Setup script for ShadcnBlocks registry in a project.
# Retrieves the API key and configures components.json.
#
# Usage: bash setup-shadcnblocks.sh [project-dir]
#
# The API key is resolved in this order:
#   1. SHADCNBLOCKS_API_KEY environment variable
#   2. 1Password CLI (customizable via OP_SHADCNBLOCKS_REF)
#
# Prerequisites:
#   - components.json must already exist (run `npx shadcn@latest init` first)
#   - jq must be installed
#   - Either SHADCNBLOCKS_API_KEY is set, or 1Password CLI (op) is available
