Interactive 3D jelly ghost with draggable limbs and wobble

GOAL: Build a single self-contained HTML file using Three.js (load from a CDN): an interactive 3D page called "Jelly Ghost". MOTION: Viewport 1280×810, white background. THE GHOST - Light grey opaque ghost made from a LatheGeometry profile (dome head, straight body) with about 18 radial segments - Hem made of 6 downward cones around the bottom edge - MeshStandardMaterial, matte (roughness ~0.4), no transparency, no refraction, no clearcoat - Face: two black flattened-sphere eyes and a black flattened-sphere mouth, positioned on the front - Two arms made of standard capsules sticking out diagonally - Lighting: one hemisphere light plus one directional light, no shadow maps - A flat light-grey circle on the floor as a shadow under the ghost - Idle: ghost bobs up and down slightly SCENE PROPS - Three stylized ghosts (purple, green, pink) sitting on the floor to the sides - A few jelly beans made from geometric icosahedrons (red, yellow, orange, purple) INTERACTIONS - Drag the head upward: the whole ghost scales on the Y axis from its bottom (max ~2.3x) - Drag both sides apart (two pointers, or hold Shift for the second): the whole ghost scales on the X axis (max ~3x) - Drag an arm: a grey cylinder "stick" stretches from the arm tip to the cursor; the arm itself does not deform - Drag the hem: same stick effect from the bottom - Grab the body and release with movement: the ghost moves rigidly with the cursor, then on release follows a parabola, stops on the floor, then after about 1 second slides back to its start position in a straight line at constant speed - On release after stretching: the scale goes back to 1 with a short, damped wobble (2–3 oscillations) - No collision with props
