+steps:
+  - headline: Set tables and a question
+    description: >-
+      Tables of four or five are set with paper tablecloths and markers. A
+      single overarching question is posed for all tables.
+  - headline: First round
+    description: >-
+      Participants converse at their starting table for twenty to thirty
+      minutes, writing and drawing key ideas on the tablecloth.
+  - headline: Rotate
+    description: >-
+      One person stays as "table host" while others disperse to new tables.
+      The host briefs newcomers on the prior conversation; a new round
+      begins.
+  - headline: Harvest
+    description: >-
+      After two or three rounds, the whole group gathers and tables share
+      emerging themes, patterns, and surprising insights.
+outcome: >-
+  Ideas cross-fertilise across the whole group; collective intelligence
+  surfaces that no single conversation would have reached.
+practice: >-
+  Keep the question open and juicy. The tablecloths matter — people who
+  doodle engage more deeply than those who only talk.
