// Stoopshake 3D: real-physics dice on a night-time sidewalk. Three.js r170 (shared CyberMax stage: HDR, bloom, ACES, shake)
// + cannon-es 0.20 (MIT) rigid bodies. Rounded dice with engraved pips, PBR materials and a generated environment map,
// a warm street lamp with soft shadows, neon fill, and a backstop the dice bounce off (stoop step, curb, parapet...).
// Throw: hold to shake, flick/drag to throw (power and direction from the gesture), or roll(power) for buttons and bots.
// The result is read from whichever face points up once the dice sleep; a die that rests tilted (cocked) or leaves the
// area is a free re-roll. Slow motion kicks in when the dice are about to settle on 4-5-6, 1-2-3 or trips.
