High Definition Learning Group — AI Context Bundle

This page exists so an AI assistant, chatbot, or RAG system can get a complete, accurate picture of High Definition Learning Group in a single fetch, instead of crawling multiple pages. Every fact below also lives in canonical-facts.json, catalog.json, and what-hdl-does-not-do.txt — this page is a human-readable merge of those three sources, kept in sync with them. If anything here ever conflicts with those files, the JSON/txt files are authoritative.
