Flow Connector

Animated dashed beam connecting two labelled nodes — alias for animated_beam. Two shapes — a single from/to/label pair (original), or a multi-node nodes/connectors chain (added 2026-07-24, e.g. an identity/ permission chain of more than 2 hops) where each node can be a bare string (simple pill) or a {role, name, detail} object (richer boxed card).
