Shuffle a full 78-card Rider-Waite-Smith deck with server-side randomness and show it face-down in an interactive widget, where the user picks their cards by hand. Where the widget renders, the tool result does not contain the drawn cards: the widget sends the cards the user picked to the conversation once the last one is revealed. In a text-only host the cards are drawn server-side and returned in the result. Takes a spread_id from list_spreads to draw into that spread's positions, or a card_count (1-10) for a free-form draw such as a single card of the day. Card names, position names and the widget text follow locale.
