# AutoBlogger CI/CD Pipeline
#
# Triggers on every push to main. Runs PHP lint and coding standards checks,
# packages the plugin into a clean zip (excluding dev files), and deploys it
# to the live WordPress site via the deploy-receiver mu-plugin REST endpoint.
#
# Required GitHub Secrets:
#   DEPLOY_URL  — https://peptiderepo.com/wp-json/autoblogger-deploy/v1/deploy
#   DEPLOY_KEY  — The token matching AUTOBLOGGER_DEPLOY_KEY in wp-config.php
#
# @see .github/mu-plugins/autoblogger-deploy-receiver.php — Server-side endpoint.
# @see scripts/deploy.sh                                   — Manual deploy script.
