The camera target was the sim tile, which jumps 8 px per movement window, and the follow was a constant-speed chase that stopped abruptly. Now the target is the render-side lerp position and the camera closes the gap exponentially, so it accelerates and settles smoothly. Also spawns the first NPC and switches the game to World::blocked.
