/**
 * /api/pastdoor-health — liveness check + per-host smoke test surface.
 *
 * Was at /api/health but renamed 2026-05-04: nginx on Kamatera routes
 * /api/health/* to Site Factory (per `feedback_pastdoor_route_collisions.md`).
 * The old path was unreachable — every health probe was hitting Site Factory.
 *
 * Update deploy-pastdoor.sh and smoke-test.sh to call this URL.
