X-Robots-Tag rather than the robots.txt Disallow alone, for the same
reason the staging rule uses one: a Disallow blocks crawling, not
indexing, so a URL found from an external link can be indexed without
ever being fetched — and blocking the crawl means the noindex is never
seen. Both mechanisms are applied to /admin and /cms-api.
The existing CSP is frame-ancestors only, which restricts who may embed
the site rather than what a page may load, so it cannot break the panel.
