+steps:
+  - headline: White Hat — facts
+    description: >-
+      The group considers only information and facts: what is known, what is
+      missing, what data is needed.
+  - headline: Red Hat — feelings
+    description: >-
+      Each person expresses gut feelings and intuition, without needing to
+      justify them.
+  - headline: Black Hat — caution
+    description: >-
+      The group identifies risks, difficulties, and what could go wrong,
+      without being dismissed as negative.
+  - headline: Yellow Hat — benefits
+    description: >-
+      The group names the value, benefits, and optimistic possibilities of
+      the idea.
+  - headline: Green Hat — creativity
+    description: >-
+      The group generates alternatives, provocations, and new ideas without
+      critique.
+  - headline: Blue Hat — process
+    description: >-
+      The facilitator manages the sequence, summarises, and defines next
+      steps.
+outcome: >-
+  The group explores a topic thoroughly without arguments tangling
+  perspectives; each mode gets its full attention.
+practice: >-
+  Keep hat time short and clearly signposted. The hardest discipline is
+  staying in one hat — if black-hat thinking creeps into yellow-hat time,
+  name it and return.
