Playable pixel-art football stadium game on a floating island

GOAL: Build a real-time pixel-art isometric diorama of American football on a floating island stadium, as a single HTML page using three.js (WebGL). MOTION: The island hangs in a night sky: layered rock strata underneath, hanging stalactites with glowing crystals, waterfalls spilling off the edges, and small floating islets with pines drifting nearby. On top: a full field with striped turf, yard numbers, hash marks, team-coloured end zones with names, goal posts and pylons. Tiered stands on three sides are packed with an instanced crowd in team colours that bounces, does the wave and fires camera flashes. Add a press box, four light towers with beams, a jumbotron, team benches, food trucks, string-lit pines, a blimp, and a rock stage with a band (two guitarists, a singer and a drummer) headbanging on the plaza. Render at low resolution with an orthographic camera, snap colours to a fixed 64-colour OKLab palette with ordered dithering, draw depth outlines, and add a pixel bloom for lights and sparks. Play 7-a-side, two original teams. Formations, a snap, shotgun passes and inside runs. Routes (go, slant, out, post, curl, corner), man coverage with cushion, a deep safety, a pass rush with blocking and the occasional free rusher. Passes are solved ballistically to where the receiver will be. Catches, break-ups and interceptions depend on separation. Ball carriers steer around defenders, juke, break tackles; pursuers take intercept angles; blockers pancake. Tackles, sacks, out of bounds, first downs, turnover on downs, safeties, touchdowns with an automatic PAT, and a running game clock. Effects: a ball trail that turns to fire on deep throws, slow-motion catches, big hits with screen shake, shockwave rings and chromatic aberration, turf spray on jukes, a glowing first-down line. Touchdowns fire pyro jets, confetti cannons, a fireworks volley (peony, ring, willow, crossette, heart), colour sweep beams, strobing towers and a flashing jumbotron. Click anywhere to launch a firework. Weather: clear, rain, and storm with lightning. Night and dusk lighting. Sound: an original rock track synthesized with Web Audio (drums, distorted double-tracked guitar, bass, lead), plus crowd noise, a referee whistle, hits, thunder and fireworks. UI: a broadcast scorebug with down and distance, arcade callouts (TOUCHDOWN, BIG HIT, JUKE, PICKED OFF), a play-by-play feed, and buttons for sound, lights, weather and hype. Original characters only, English UI, responsive down to phone width.
