import { Suspense, type ReactNode } from 'react'

// Validation level is 'experimental-manual-error' (set in next.config.ts).
// No implicit validation — only segments that explicitly opt in via
// `instant` are validated. When validated, the level is error,
// applying in dev AND build (build fails on violations).
//
// Children are wrapped in Suspense so that pages with runtime data
// accessed at the top of the page don't fail static-shell validation
// (the Suspense fallback renders into the static shell). Instant
// validation flags "Suspense too high for instant navigation" as an
// instant-specific violation when it runs.
