+/**
+ * v1.4.43 W11 — insights mother-page dynamic-skeleton guards.
+ *
+ * The three `next/dynamic` loading placeholders for
+ * `DailyBriefing` / `CorrelationRow` / `TrendsRow` used to reserve
+ * heights (`h-48` / `h-32` / `h-64`) noticeably shorter than the
+ * loaded content (~24 rem / ~20 rem each), which CLS-shifted the
+ * page on slow networks. They also lacked `motion-reduce:animate-none`,
+ * so motion-sensitive users saw a continuous pulse.
+ *
+ * This textual guard pins both the larger reserved heights and the
+ * motion-reduce class. The check is intentionally simple — render-
+ * mounting the page would haul in TanStack-Query / Auth / I18n
+ * scaffolding for a property a substring search already proves.
