Jithox EU Energy Label Preflight

Read-only EU energy-label preflight over the official EPREL Public API (live mode) or a clearly-labelled SYNTHETIC fixture (dev/test) — provenance.sourceAuthority names which on every result. Search and structure public supplier-declared energy-label records BEFORE an agent or operator relies on them. All data is supplier-declared and NOT verified by Jithox; a no-match is never 'not registered'; missing/stale/unavailable is never a verdict. Never a conformity, CE, GPSR, safety or market-access determination. No registration, upload, mutation or autonomous action.
