The game tab held a "Press Play" hint where the picture belongs. It now
previews the scene through the active camera, and says "No active camera"
when none is switched on.
Camera choice and its world position moved into activeCamera.ts so both
are testable without Pixi. Entity.x/.y are parent-relative; the viewport
used them as the camera's spot, which framed a parented camera at the
wrong place.
