/**
 * B2B admin scan (D19 step 2) — hits every read endpoint the wholesale side of
 * the admin panel uses on a normal working day, looking for things that are
 * OUTRIGHT BROKEN (500s, crashes, empty required shapes).
 *
 * Scope per the owner: wholesale customers, sales experts, products and
 * variants, wholesale orders, documents. Retail/storefront surfaces
 * (single*, wallet, comments) are D13 — preserved, not scanned.
 *
 * This is a breakage scan, not a parity audit: a 200 with plausible data
 * passes. Anything non-2xx is reported with its body so it can be triaged.
 *
 * Usage:  node scripts/scan-admin-b2b.cjs [apiBaseUrl]
