Whether the orbit turntable is currently spinning the camera. While it
is, a story step must not swing the camera to the author's azimuth: the
flight keeps the live direction (keepOrientation) and only the target
and distance travel, so the spin continues uninterrupted around the new
point of interest.
Snake_case rendering overrides — the authored viewer_config path.
OptionalemitThe two story events (SOUND_SPEC.md §4.3): waypoint-departed fires the
moment the matched waypoint changes away from one; waypoint-arrived
fires after the new waypoint's flight resolves (or immediately after a
snap, or immediately when it has no camera block). A flight the visitor
cancels still resolves and still arrives (completed: false); a flight a
NEWER waypoint superseded does not arrive at all — the visitor has moved
on, and its narration must not overlap the new story's.
Instant application of the authored pose (the load-time framing).
