+        Gravity as an effect, or gravity as a force — either way you look at it,
+        it is a computational overhead issue.
+      </p>
+      <p>
+        In this interpretation, gravity is not first pictured as a marble being
+        pulled through a spatial background. It is treated as the visible cost of
+        maintaining global/local consistency: update delay, constraint propagation,
+        bookkeeping pressure, and loop-rate skew inside the information process
+        that renders distance, inertia, and apparent curvature.
+      </p>
+      <p>
+        That does not prove a theory of gravity. It states the research posture:
+        when a physical effect looks like force, curvature, delay, or resistance,
+        ask what computational overhead the coupled system is paying to keep the
+        event admissible.
