Card types

A matched answer usually carries one of these cards in card.type, with data that follows the card's JSON Schema. card is null when the best type isn't in your accept list, and new types can appear: show text for any card you don't render.

Not answered yet: the API sends no quiz or movies cards for now, and such questions come back matched: false (not billed). Both types stay in the contract, so handle them like any other type, or show text.

How the catalog is cut: a new type when the data shape differs; a new layout when only the presentation differs; a new kind when only the meaning differs.

Times inside card data are ISO 8601 with the location's offset, or local HH:MM where the schema says so. Values a source does not provide are null, never guessed: MET Norway, for example, gives precipitation amounts but no probabilities outside the Nordics. Amounts follow the card's own units (weather.forecast reports precipitation in units.precipitation).
