A massive sci-fi hangar with 32 numbered bays, in NFL order. Each bay holds a dormant power core with the team logo on its front plate; the plate below reads the team name and AVAILABLE. Steel, hazard amber, an overhead rail with blinking warning lights and drifting haze.

When a team sells (Full): a ceiling arm races along the rail to the bay, drops, clamps the core in a spray of sparks and carries it to the central platform while the other bays dim. Legs, torso, arms and head snap on one after another, each with a jolt and sparks; the core ends up in the chest and the team logo locks onto the chest plate. Light in the team colors surges up through the suit and the visor flickers on. Hero shot: the mech turns toward you with a push-in and a big plaque shows SOLD and the buyer's name (long names are squeezed, never wrapped). The mech then returns to its bay. Quick mode (about 2 s) builds the mech in place. In the grid a sold bay shows the powered-up team-colored mech with its logo on the chest and a soft bay light; the plate shows SOLD, the buyer and a small logo. A reload restores this.

At sell-out the bay lights switch on in a wave, the whole lineup powers up together, the main hangar doors slide open with bright light flooding in, and SOLD OUT appears in the title band. Then the hangar returns to normal.
