healthcheck.js

// Docker HEALTHCHECK probe — not imported by the app (see Dockerfile note).
//
// Deliberately probes a RENDERED page, not /api/health. /api/health is dependency-free
// by design, so it answers 200 while every marketing page 500s on an i18n or
// message-catalog regression — and since nothing declares `depends_on: service_healthy`
// for this service, the only consumer of this probe is the STATUS column a human reads.
// A cheaper probe that proves less is a bad trade there. /en proves the App Router
// served HTML with messages resolved; the 5s timeout was never what a render failed.
