-The Behaviour tab beside the 3D view (the button under the moves, or View > Panels) edits the
-port's `[behaviour]` graph as rules. The outline on the left lists what starts a rule: an event,

+The Behaviour tab edits the port's `[behaviour]` as rules, grouped by what starts them: an event, a

+stored canvas order, each block's `(y, x)`, top first: `+ Rule` adds a rule last, dragging a rule's
+frame trades places with its own trigger's rules only, and in All rules › Canvas dragging a node can
+change it. In Canvas a block's `out` wires to the next block's `in` or to a move's `play`; a move's
