/* SOLID CITY — THE HYPER TRAIN & WORMHOLE (2026-10-11, the King's word)
 * "I like it but i wanted a hyper train through the tunnel to get to the
 *  other side through a worm hole."
 *
 * THE DEPARTURE (station at the Bore mouth) -> 800m ride down the Bore ->
 * THE WORMHOLE (the only way through) -> transit -> THE ARRIVAL (Starwell).
 *
 * Design law: mathematical beauty, no excess words. Acceleration is physics
 * (ease-in, cruise, ease-out). The wormhole spiral follows the golden angle.
 *
 * Self-contained ES module. Local frame: mouth at (0,0,0), floor y=0,
 * tunnel extends along local -Z. The placer sets world position.
