The Twilight Triad
Three independent spaces, composed through render-target portals.
A triangle of doorways whose loop does not close:
measured holonomy ….
A · Courtyard
B · Study
C · Corridor
— doorframes glow the color of their destination.
Try it: A → C → B, then step back to A through the direct amber door.
Compare your arrival bearing with the route you left by.
