Live camera accessor, NOT a captured instance: the camera is the one
component the scene manager REPLACES at runtime (perspective ↔ ortho
swap in camera-mode.ts). A captured reference goes stale after the
first V-key mode switch, freezing the scale bar on the abandoned
camera (ortho zoom then never updates the label).
