get_data_app_card_image

Export one mounted Data app card by its exact cardId from list_data_app_cards. Returns a PNG as base64 data with pixel width/height, filename, source IDs, and current view metadata for slides or documents. Captures the current rendered card, including filters and presentation; no clipboard, download, navigation, or data writes. Hidden, duplicate, loading, failed-to-load, changing, oversized, or unsupported cards fail explicitly. Decode data as base64 to save a PNG; do not print the image bytes as text.
