+/** @odoo-module
+ *
+ * LaundryContextStore — small reactive store, owned by PosStore, that
+ * holds the per-order laundry context (type / attributes / delivery)
+ * keyed by order uuid.
+ *
+ * Why a separate store?
+ *   The POS related-models engine wraps records in a field-aware proxy.
+ *   Writing custom properties (not declared in _load_pos_data_fields)
+ *   directly on the order does NOT trigger OWL reactivity, so the
+ *   context panel never re-renders after the popup confirms.
+ *
+ *   Exposing the fields via _load_pos_data_fields is proven to crash
+ *   POS at boot (`lines is undefined` in _computeAllPrices), so the
+ *   only safe path is to keep these values OUTSIDE the engine, in a
+ *   plain OWL reactive object that components can subscribe to.
+ *
+ * Contract:
+ *   pos.laundryContext.get(uuid)  → reactive object with keys:
+ *                                    { type_id, attribute_ids,
+ *                                      is_delivery, delivery_address,
+ *                                      delivery_scheduled_at }
+ *   pos.laundryContext.set(uuid, patch)
+ *   pos.laundryContext.clear(uuid)
+ *
+ * Persistence is independent: the same values are mirrored on the
+ * order as primitives (set in pos_store_patch.js) and shipped to the
+ * backend via PosOrder.serializeForORM (see pos_order_patch.js).
