// Same violation as `bare/page.tsx`, but with `instant = { level:
// 'warning' }`. Per-segment override lowers the level from the configured
// 'experimental-error' to 'warning', so build validation does not fire and
// the build stays clean even though the violation exists. Dev still shows
// the instant redbox.
