    FNXC:TaskDeleteAttribution 2026-07-30-06:20:
    Header keys are LOWERCASE and now include the client stamp. `app/api/client.ts` builds request
    headers through a `Headers` object (which lower-cases every key) and sets
    `x-fusion-client: dashboard-ui` on every dashboard-originated request so the server can attribute
    the caller — the FN-8609 delete-attribution surface.

    This asserted `"Content-Type"`, and `objectContaining` compares keys case-SENSITIVELY, so it broke
    on the casing alone. Rather than just lower-casing the key, this now pins the client stamp too:
    that header is the point of the feature, and nothing else in this file covered it.
