Hyena Clan Calls Lab (2D)

This 2D companion models the acoustic side of the 3D clan scene as coupled phase oscillators: each hyena whoops on its own internal rhythm, but calls from clan members within earshot pull that rhythm toward theirs — the same Kuramoto coupling model used to explain synchronized firefly flashing and clapping audiences. Push call volume up and background noise down and the clan's whoops lock into a synchronized chorus, visible as the flash rings firing together; do the opposite and the calls stay scattered, exactly as real hyena clans lose coordination in noisy or spread-out conditions.
