Agentic Cruise — SS Meridian: 8 crew + 7 passenger groups visibly live a 7-day voyage across 5 decks
A 3D AGENTIC demo: SS Meridian — 8 named crew and 7 named passenger groups visibly live a fictional 1930s art-deco 7-day voyage across 5 decks. Each passenger has a VISIBLE BRAIN — a captain planning the storm route, a dowager planning the jigsaw puzzle. Like The Love Boat meets Knives Out at sea.

## What this is
A 3D recreation of the SS Meridian, a fictional 1930s art-deco cruise ship on a fictional 7-day voyage. Eight named crew and seven named passenger groups visibly live across five decks. The Bridge is the dawn-blue captain's wheel + brass speaking-tube + chart-table. The Dining Room is the art-deco-gold long table with brass chandeliers and potted palms. The Pool Deck is the noon-cyan deck-chair lineup with striped umbrellas. The Stateroom Corridor is the warm-amber animated-porthole hallway with brass sconces. The Engine Room is the industrial-orange boiler bank with Engineer Pip's gauges singing. The entire ship rolls plus-or-minus two degrees on a slow sine wave through the whole scene — drinks slosh on the dining table, deck chairs sway, palm fronds tilt. Capt. Whitford Sebold (jolly captain — yes, this is the same Whitford as the R17 mall and R18 office crossovers, on a well-deserved vacation), Engineer Pip Crowsbridge (boiler maintenance), Maitre d' Reggie Halloway (dining seating chart), Bandleader Tess Felling (jazz quartet, "S'Wonderful" tonight), Doctor Wendell Carrow (cozy diagnoses), Steward Mara Greenfell (corridors), First Mate Bren Halberton (bridge), Sommelier Vana Trill (wine cellar). Passenger groups Dowager Mrs. Pemberton (jigsaw — 847 piece "Mediterranean Sunset"), Honeymooners Jules + Ada Mendoza (dance lessons every afternoon), Mystery Author Indira Pell (typewriter on the deck — Day 4 chapter 12), Detective Halloran (yes, the same Halloran from the heist demo — on vacation, but watching), and three more. Each passenger group has a goal, a need, a plan, a current step, and a mood — visible in the AGENTIC THINK PANEL. Per-deck HUD shows "DECK 3 OF 5: POOL DECK · DAY 4 · 47 PASSENGERS SUNNING." Ship's Log overlay top-left tracks voyage progress. Eighty ambient sunning passengers. Nineteen director cameras cycle.
The voyage *remembers*. localStorage saves the day counter (Day 1 → Day 7 → next voyage), total voyages completed, ports visited, dance partners paired (Jules+Ada count up to 14 dances across cycles), jigsaw progress (Mrs. Pemberton at piece 423 of 847), and postcards mailed. Each ten-minute reseed advances voyage day, ports the ship at the next harbor, and rolls fresh weather.
You don't play it. You watch it. And it remembers.
## Why this is mind-blowing
The chyron is the secret weapon: "Day 4 — Mrs. Pemberton fits jigsaw piece #423 of 847. Jules + Ada dance their 9th lesson — Tess plays 'S'Wonderful.' Detective Halloran spots an unsigned passenger card in the dining ledger." That single line stitches three decks in one beat — Mrs. Pemberton on the Stateroom Corridor jigsaw close camera with the sailboat-piece settling into the Mediterranean blue (decision diamond as she finds the corner, jigsaw counter ticks 423/847), Jules + Ada on the Pool Deck dance close camera with Tess's clarinet rolling "S'Wonderful" through the brass (interaction sparkle as their hands meet, dance partner counter ticks 9), and Detective Halloran on the Dining Room ledger close camera with the unsigned card pinned (decision diamond as Halloran notes "investigate Day 5", relationships graph adds suspicion edge). Multiply that by fifteen named souls each with a brain panel showing goal/need/have/plan/step/mood (Detective Halloran's plan literally reads "spot anomaly → cross-reference passenger list → ask gracious questions at dinner → solve by Day 7 NOT before"), a ship rolling ±2° through the whole scene, per-deck HUD updating live, a Captain Whitford crossover from R17 mall + R18 office on his well-deserved vacation, and a Love-Boat-cozy chyron beating a 7-day voyage arc, and you've got a Knives-Out-at-sea stream that genuinely earns its agentic scope. ALL FICTIONAL — no real ships, no real captains, no real detectives.
