"""ghost — recipe-specific functional test (Phase 2 P3).

Ghost exposes a public JSON Content API at `/ghost/api/content/settings/` which returns the
site's public configuration (title, description, etc.) WITHOUT requiring an API key for the
basic settings endpoint. Some Ghost versions DO require a key here — accept either:
- 200 with JSON envelope: API alive + accessible.
- 401/403 with JSON error: API alive + correctly gating.

Distinguishes "ghost-server JS process is up + serving its API" from "a static page is served
at /" (which the parity test catches by 200).

A wedged Ghost backend returns 502/504 or 503. A misrouted nginx returns 404.
