/**
 * The address step of the conversational order flow.
 *
 * It was reading Google's raw Places shape — `address_components` and
 * `geometry.location.lat()` — from a value that never has either.
 * `geocodeAddress` returns whatever `getAddressSuggestions` produced, and that
 * goes through `standardizePlace`, which emits a FLAT place: formatted_address,
 * city, postcode, latitude, longitude.
 *
 * So the forEach never ran and both coordinates came back undefined. Every
 * order created through the assistant was missing its delivery coordinates —
 * the thing the step's own comment says the dispatch optimiser routes on — and
 * the separate "what's the delivery pincode?" step fired every time because
 * nothing had ever set it.
