/* =========================================================================
   GROUP — "One group. Five companies."
   Signature set piece: a Three.js constellation. The SAA core sits at the
   centre with five company nodes in orbit, joined by filaments of light.
   Desktop: the section pins and the system turns to bring each company
   forward while the text panel swaps. Phones and reduced motion: the scene
   sits in a sticky band and the company cards scroll beneath it.
