// Pure — no network, no fs. The fixture below is a REDACTED copy of a
// real /admin/status.xml pulled from a lab DBS-210 during the DECT
// spike. MAC, IP, RFPI, and firmware server URL are all changed to
// obviously-fake values so this file is safe to commit and safe to
// leave in CI logs. The XML SHAPE (tag nesting, whitespace, encoding
// oddities like `text/text` mimetype on the wire) is preserved
// verbatim — that's exactly what the parser has to be robust against.
