Pixel-art ice hockey game with a retractable dollhouse-style arena

GOAL: Make a 3D pixel-art ice hockey game: an old timber indoor arena on a floating slab of frozen ground, rendered as a real-time three.js scene through a low-res orthographic isometric camera with depth outlines and a 64-colour OKLab palette; quarter-turn rotation where the two walls/stands nearest the camera lift away like a doll's house. Five skaters and a goalie a side (home Otters in green, visiting Foxes in orange), box-rig players with IK, numbers on their backs, helmets with visors, sticks laid from blade to top hand. Real rules: three 20-minute periods on a four-sided scoreboard hung over centre ice (clock runs only in play), faceoffs at the correct dots with a striped referee dropping the puck, goalie freezes for whistles, two-minute penalties in a glassed penalty box with power plays, body checks into the boards that rattle the glass, pucks over the glass into the crowd, sudden-death overtime, goal horn and red light, fist bumps along the bench, a handshake line at the end. Momentum skating with hockey stops, five-role team shape, passes solved from ice friction, shots aimed at the open corner. The ice is a canvas the skates scratch; between periods a resurfacer drives laps from its corridor and wipes it clean. Instanced crowd of ~900 fans who stand for goals, groan at posts and do the wave; lights Game / Dim / Show (spotlights and phone lights). Side panel with live score, clock, rosters, press-box commentary and controls. Original fictional teams, sponsors and town; English UI.
