Same exception as the motion watch: busy in Sample alignment is the alignment itself, and the sample motion is watched in these very views - the curtain hid exactly what the user needed to see. Gated at both style call sites (sample camera and the Axis views); the session-driven 'In viewing mode' badge is unaffected. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
