+* Retail camera-boom measurement (2026-06-08): confirm the eye-hover jitter at rest AND read the
+* CameraManager smoothing (stiffness) + SmartBox boom offset, so R-A4 matches retail rather than guesses.
+* HOLD THE CAMERA STILL during this capture (~300 frames, a few seconds).
+* SmartBox+0x08 viewer Position; frame.m_fOrigin x/y/z = ecx+0x44 / +0x48 / +0x4c (raw float bits).
+* viewer_sought_position+origin (pre-collision desired eye) = ecx+0x94 / +0x98 / +0x9c. cell = ecx+0x0c.
