NSHapticFeedbackManager .alignment at propose()'s change edge — the
one funnel every retarget commits through, whose existing guards
(value-equal refusal, hold freeze) already make firings per-landing-
spot rather than per-pixel; withdrawal stays silent (losing a target
is not an alignment), and the external-file mode gets nothing. Force
Touch hardware only, silent no-op elsewhere; performanceTime .default
syncs the tick to the reflow the change triggers. The performer rides
an injectable seam beside holdTimeout for the same reason it has one.
Drag-perf card 11b85111 — the cluster's last.
