+steps:
+  - headline: Generate topics
+    description: >-
+      Each participant writes topics they want to discuss on sticky notes,
+      one topic per note, and posts them to a shared board.
+  - headline: Dot vote
+    description: >-
+      Each person places dots on the topics they most want discussed, voting
+      for their own and others. The board is sorted by dot count.
+  - headline: Timed rounds
+    description: >-
+      Topics are discussed in order, each starting with a three-minute
+      timer. A thumbs-up vote extends by two minutes; majority no-vote moves
+      on.
+  - headline: Review and capture
+    description: >-
+      At the end, the group reviews what was discussed, captures actions,
+      and notes topics still open for next time.
+outcome: >-
+  The group discusses what the people present actually care about, in
+  priority order, with no agenda imposed from above.
+practice: >-
+  The three-minute start is short by design — it forces focus. Don't skip
+  the voting; it surfaces the real priorities without debate.
