Container Hero

A one-screen hero on a plain background: a 20ft shipping container built as a real box in CSS 3D, three quarters on, hangs from a crane hook on four slings over its soft shadow. It swings on its cable with a little wind and takes a shove from a passing pointer; the loop runs only while the hero is on screen, and under reduced motion the crate hangs still. No dependencies; it scales to the stage, so it fits a phone, a short landscape screen or a desktop alike. Theme-aware.
