name: Deploy to Railway

# Deploys Dealix backend to Railway using Railway CLI.
#
# Setup (one-time, by Sami):
#   1. Go to https://railway.app/account/tokens
#   2. Create a new token named "github-deploy"
#   3. Copy the token
#   4. Go to https://github.com/VoXc2/dealix/settings/secrets/actions
#   5. Add New repository secret: RAILWAY_TOKEN = <paste token>
#   6. Optional: Add RAILWAY_SERVICE_NAME = dealix (if service name differs)
#
# After setup: every push to main auto-deploys, OR trigger manually
# via Actions tab → "Deploy to Railway" → Run workflow.
