// MagicCardPreviewSource: ICardPreviewSource implementation for Magic the
// Gathering. Calls Scryfall's search endpoint at
//   https://api.scryfall.com/cards/search?q=name:"<name>" AND set:<setCode>
// and returns `data[0].image_uris.normal`. Mirrors the established
// `src/components/magic/SelectedMtgPanel.tsx::getImage`, including the
// `&` -> `and` substitution in the card name.
