The 2026-05-18 retail-chase-camera spec scoped collision out citing "retail
doesn't raycast." Phase A8.F falsified that (SmartBox::update_viewer DOES sweep
viewer_sphere); mark the note superseded and point to the A8.F spec.

Spec for porting retail's CameraManager + CameraSet behavior to a new
RetailChaseCamera class, controlled by a CameraDiagnostics toggle so the
user can A/B against legacy ChaseCamera. Covers six retail behaviors:
exponential damping (stiffness*dt*10), 5-frame velocity-averaged slope
alignment, mouse low-pass (0.25s window), held-key offset integration,
auto-fade <0.45m, and independent translation/rotation stiffness rates.
Brainstormed end-to-end before any code change.
