+        v1.4.28 R3d (BK-UI-StatusSchlaf) — the six sibling sub-pages all
+        mount `<InsightStatusCard>` underneath the chart so the user
+        gets a written per-section AI assessment. Sleep has no
+        `/api/insights/sleep-status` route yet (the v1.4.23 schema
+        landed the data but the assessment-generation pass was deferred
+        to the v1.5 iOS sprint where the Apple-Health sleep snapshot
+        will inform the prompt). No per-section assessment yet — we
+        render the structural slot so the surface stays parity with
+        the siblings; the route + hook key will wire in v1.5.
