"""Customer-specific pricing engine for the B2B ordering portal.
The backend is the single source of truth for prices — the frontend never
computes a final price. :func:`resolve_price` returns a fully-attributed
:class:`PriceResolution` so every order line, and any future report, can explain
exactly which rule produced the number.
Resolution priority (highest wins):
1. **Quote-only** — the product requires a manual quote, or the customer has a
``quote`` price rule for it. No automatic price.
2. **Fixed / contract** — a :class:`CustomerProductPrice` for this customer +
product (quantity tiers may refine it).
3. **Price list** — a :class:`PriceListItem` from the customer's assigned price
list (quantity tiers may refine it).
4. **Base + discount** — the catalogue list price, optionally reduced by the
customer's default discount percentage.
5. **Quote fallback** — no resolvable price ⇒ treated as quote-only.
All prices are GST-exclusive.

"""Xero integration layer for the ordering portal.
This is a **clean, stubbed interface**. No Xero credentials are hard-coded — all
configuration comes from environment variables (``XERO_*``). When credentials
are absent (the default in dev/alpha), the service runs in "stub" mode: it
records what *would* be sent and returns a deterministic fake invoice id so the
rest of the order lifecycle can be exercised end-to-end.
To go live, implement the real HTTP calls inside :func:`_submit_to_xero_api`
(see the TODOs) — no caller needs to change.
Service responsibilities (per spec):
* Map a customer (ClientAccount) to a Xero contact.
* Map catalogue products to Xero item codes.
* Create a draft invoice equivalent for a confirmed order.
* Record Xero response ids/status (via XeroSyncLog, written by the caller).
* Handle failures gracefully (never raise into the request path).
