GoogleCloudPlatform/cortex-data-foundation — reverse-engineered prompt

Build me a Google Cloud data foundation starter kit like Cortex Framework.

I want a deployable project that helps a company bring data from SAP, Salesforce, Oracle EBS, marketing platforms, Google Ads, GA4, Meta, TikTok, YouTube, CM360, LiveRamp, and sustainability sources into BigQuery. It should include clear configuration files, deployment scripts, and docs so someone can choose workloads, set up the right Google Cloud projects, run a quick demo with sample data, or prepare a production deployment.

Please include ERD style documentation for the supported data sources, explain what each workload is for in plain English, and make the deployment flow easy to follow from prerequisites through execution. It should support optional setup choices like separating access by project, using Cloud Build, external datasets, telemetry, turbo mode, common dimensions, and dependent DAG tasks.

Also include guidance for using Looker or Looker Studio dashboards after deployment. Look up the current Google Cloud Cortex docs online if needed.
