/* Solid City — places THE IMPERIAL COLOSSEUM (public/city/colosseum-imperial.js)
   far south beyond the Ancestral Roads.
   Lazy: imported after the city is built; any import/build error is caught and the city carries on.
   The terrace height adapts to the terrain at runtime. Permanent at load.
   Adds: collision (userData.footprint), a radar marker 'IMPERIAL', a Hyper Controller
   stop, and a Watch (GRAND TOUR) caption. */
