// R-1028/R-1045: Plex's „claimed" can be probed only with Accept: application/json (it answers XML otherwise —
// measured 2026-10-15 on Tester 1). The probe with `accept:` reads the JSON field; without it the same server reads
// „not JSON" and the gate stays closed. COMPANION RED-PROOF: ignore p.Accept in probeOnce → the first case fails.
