+steps:
+  - headline: Frame the round
+    description: >-
+      The facilitator explains that each person will have up to one minute
+      to share, with no cross-talk or responses.
+  - headline: Go around
+    description: >-
+      Each person speaks in turn, proceeding around the circle. Passing is
+      always an option.
+  - headline: Note themes
+    description: >-
+      The facilitator notes recurring themes without commenting. These
+      become the basis for the discussion that follows.
+outcome: >-
+  Everyone has been heard; the group has a shared sense of where things
+  stand and what themes deserve further discussion.
+practice: >-
+  Use a talking object to signal whose turn it is. Keep time gently — a
+  soft chime works better than a timer. If the group is large (12+),
+  consider breaking into smaller rounds.
