## Scoring algorithm

1. For each type 1–9, sum the user's raw 1–5 responses to that type's four items (range 4–20). No reverse-scoring.
2. The highest total is the **dominant type**.
3. The higher-scoring of the two adjacent types (the wings) is the optional **wing**.
4. Resolve the slug from the dominant type (e.g. 5 → `5-investigator`).
