Seedance Spatial Reference for Props Demo

One continuous spatial logic. Segment 1 — 15s⚡ Position 1 — Sofa Character enters, sits on the sectional. Room geometry locked from Camera A reference. ⚡ Position 2 — Lava Lamp (Prop ①) She rises, crosses to the low unit. Crouches. Touches the glass. Blue-green wax light fills her face. ECU holds because the prop detail tile told Seedance exactly what this object looks like up close. ⚡ Position 3 — CRT Television (Prop ④) She moves across the room. Stops at the set. Segment 2 — 15s⚡ CRT Television (Prop ④) → off She kills the screen. Room loses its blue static glow. Only lava lamp and table lamp remain. ⚡ Back to Sofa — Coffee Mug (Prop ②) Back to the sectional. Picks up the mug. One sip. Rain outside. Each segment is a separate Seedance generation. Same @[image] reference board. Same prop numbers. Same room. That's how spatial consistency survives a generation cut.
