A private modern museum, opened at midnight, for an audience of one. Black marble, warm travertine and champagne brass staged under theatrical spotlights: the guest walks a night atrium beneath a constellation of hanging lights, reads the couple's story as wall text by torchlight, then travels sideways through spot-lit galleries of portraits and chronology vitrines. Two set-pieces crown the visit — THE BRILLIANT, where a glass vitrine rises and a diamond ring levitates in a cone of light under the guest's own fingertip tilt, and THE VAULT, a bank-vault door whose brass wheel spins with the guest's scroll until golden light floods out and the gift suite emerges as acquisition cards stamped ACQUIRED. It closes at dawn in the registry room, where the RSVP becomes a signature in the guest book. Neoclassical piano-and-cello score, compositor-only scroll engine on a single heartbeat, hand-tuned for mobile.
