1.5.0
CardPay: granular per-field billing address prompts.
`RequiredBillingInfo` now accepts an optional `fields` object (`RequiredBillingFields`) that
controls exactly which billing fields are prompted to the end customer - only fields marked
`true` are shown. When set, it takes precedence over the coarse `details` (MIN/FULL) and the
`phoneRequired`/`emailAddressRequired` flags. Fields: `name`, `countryCode`, `postalCode`,
`addressLines`, `locality`, `administrativeArea`, `phoneNumber`, `emailAddress`.
In addition, `Engine.payBy` now honors its `requiredAncillaryInfo` parameter (previously
reserved); when supplied it overrides the value passed to the `Engine` constructor.

1.4.0
CardPay: optional visual customization of the hosted card-entry forms.
`Engine.payBy` now accepts an optional `iframeStyleConfig` parameter that re-skins the
new-card, CVV, and stored-card forms (color palette, typography, per-field states,
chrome, layout/labels, branding, and locale/RTL direction). It is transported to the
hosted forms in the CardEntry postMessage and applied by a single consolidated style
service. All fields are optional; anything omitted keeps its default styling.

1.3.8
Reverse CHANGELOG.md ordering so the most recent version appears at the top.

1.3.7
Fix broken CHANGELOG.md link in the npm README (relative link 404'd; now points to the unpkg CDN).

Documentation cleanup.

1.3.1 - 1.3.2

1.3.0
Added the GATEWAY_TOKENIZE operation for CardPay.
After the card details are accepted, the engine posts the card data to [POST] /gateway-tokenize
(same body as /tokenize, with no other parameters) instead of /charge or /tokenize.

1.2.0
CardPay: optional iframe display mode for the card-entry form.
The Engine `uiOptions` now accepts:
- `displayMode`: 'popup' (default) | 'iframe' - render the CardPay form in a separate window or an in-page iframe.
- `iframeContainerSelector`: CSS selector of an element to host the iframe inline; a centered modal overlay is used when omitted.
When embedded as an iframe, the hosted form posts results to the parent window (window.parent) and renders frame-less.
