Server logs (thanks to the user pulling them) showed the real error:
"Functions cannot be passed directly to Client Components" — the server
component page was passing formatShortDate/formatMonth as a `formatDate`
prop into TimeSeriesChart ("use client"). Functions aren't serializable
across the RSC boundary; the two previous fixes (query hardening,
Promise.allSettled) were real improvements but not the actual cause of
the reported crash.
TimeSeriesChart now takes a plain `dateFormat: "day" | "month"` string
and formats internally — BarChart was never affected (its formatValue
prop is only ever used via its own default, never passed from the page).
