+
+# Content Creation
+
+**Goal:** Generate strategically grounded text content using the Five-Model Framework.

+
+## INITIALIZATION
+
+### Design Log

+## The Five-Model Framework
+
+1. **Content Purpose** — The job to do
+2. **Trigger Map** — Strategic foundation
+3. **Customer Awareness Cycle** — Content strategy
+4. **Action Mapping** — Content filter
+5. **Badass Users** — Tone & frame
+6. **Golden Circle** — Structural order (WHY > HOW > WHAT)
+
+---
