/**
 * The AuditTrailGraphic's motion: the newest ledger entry stamps in once on
 * load (a short settle from above — an append, never a re-append, since the
 * record is immutable), and its actor avatar then carries the row's shared
 * quiet 6s ring-pulse beat (same bloom as the access tile's live grant and
 * the lifecycle tile's live node) to mark the trail as live. Under
 * prefers-reduced-motion both are removed and the ledger sits static.
