    # (SAMEORIGIN) and any CSP are stripped so the demo can embed it in the
    # in-app iframe session, and a PUBLIC-DEMO-ONLY sign-in seed script is
    # injected into the HTML <head> (it seeds a labelled throwaway demo Nostr
    # account into the :2101 origin's isolated localStorage, so IndeeHub boots
    # signed in). Upstream is pinned to a single fixed hostname — this cannot
    # be used as an open proxy.
