# Staging, Preview, and Production deployment workflow
# - Push to develop → deploys to staging
# - Pull request → deploys to preview environment
# - Push to main → deploys to production (requires approval)
#
# Required secrets (configure per environment in GitHub):
#   Staging environment:
#     - GIGALIXIR_EMAIL
#     - GIGALIXIR_API_KEY
#   Preview environment:
#     - GIGALIXIR_EMAIL
#     - GIGALIXIR_API_KEY
#   Production environment:
#     - GIGALIXIR_EMAIL
#     - GIGALIXIR_API_KEY
#
# Note: This example uses a single shared preview app. For true PR-based
# preview environments, you would need to dynamically create/destroy
# Gigalixir apps using the Gigalixir CLI.
