// services/woHeaderProfileStore.js
// Work Order print/PDF header — previously a single flat config (Admin →
// System Settings → "Header Details") burned onto every printed Work Order
// regardless of product. Now a LIST of named profiles (e.g. "Blood Bag",
// "CAPD", "Accessories"), each mapping to a set of SAP Item Groups; the
// profile actually used for a given Work Order is resolved client-side in
// work-order-print.html from the WO's product's SAP item group. Exactly one
// profile is always the Default — used as the fallback for any item group
// not explicitly mapped to a specific profile.
