FASTREGISTER

A static WhatsApp quick-registration card: a 3-step explainer (enter number, send the code, talk to a rep), a country code + phone field, and a "Send" button that opens a WhatsApp chat with that number.

{ "type": "FASTREGISTER", "params": {} }

params is currently unused — reserved by the backend contract for future configuration. The country code list is a small fixed set built into the widget (+90, +1, +44, +49, +7); there is no callback for this widget since it only opens an external https://wa.me/<number> link.

The card's border/header/text accent color reads from EcommerceWidgetTheme.fastRegisterAccentColor (defaults to WhatsApp green) instead of a hardcoded color, so it can be re-branded like the rest of the catalog. If the WhatsApp link can't be opened (e.g. WhatsApp isn't installed), a snackbar shows theme.fastRegisterLaunchFailedLabel.
