// Validation level is 'warning' (set in next.config.ts).
// Bare page/default segments get implicit validation in dev only — build
// is unaffected unless a segment explicitly overrides with `level: 'experimental-error'`.
//
// 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.
