import { Suspense, type ReactNode } from 'react'

// Validation level is 'manual-warning' (set in next.config.ts).
// No implicit validation should fire on bare pages, in dev or build —
// only segments that explicitly opt in via `instant` are validated.
//
// Children are wrapped in Suspense so that pages with uncached data
// accessed at the top of the page don't fail static-shell validation
// (the Suspense fallback renders into the static shell). Instant
// validation can still flag "Suspense too high for instant navigation"
// as an instant-specific violation when it runs.
