⚠️ Potential issue | 🟡 Minor

Keep a real paused interval in this regression test.

This only proves that one render produced a paused snapshot. It no longer verifies that progress stays frozen over time while paused, so a regression that still advances for a few frames can pass here.

Suggested change 
       await waitFor(() => {
         const next = h.render((hooks) => useParallel(hooks, paused));
         render = next;
         h.runPending(next.pendingEffects);
         const entry = next.result[0];
         if (!entry) return false;
         return Math.abs(entry.value - pausedValue) <= 0.1 && entry.isAnimating === false;
       });
+
+      await sleep(80);
+      render = h.render((hooks) => useParallel(hooks, paused));
+      h.runPending(render.pendingEffects);
+      assert.ok(Math.abs((render.result[0]?.value ?? 0) - pausedValue) <= 0.1);
+      assert.equal(render.result[0]?.isAnimating, false);

In
`@packages/core/src/widgets/__tests__/composition.animationOrchestration.test.ts`
around lines 203 - 210, The test currently only verifies a single paused
snapshot; update it to assert the value stays frozen across a real paused
interval by advancing frames/time and re-checking that progress does not change.
Specifically, after the initial waitFor that captures entry from
h.render((hooks) => useParallel(hooks, paused)) (referencing useParallel,
paused, pausedValue, next.pendingEffects, h.runPending), run several subsequent
frames (e.g., call h.runPending(next.pendingEffects) repeatedly or advance
timers) and assert each time that Math.abs(entry.value - pausedValue) <= 0.1 and
entry.isAnimating === false so the test proves no drift over time while paused.


render = h.render((hooks) => useParallel(hooks, running));
h.runPending(render.pendingEffects);
