Tarot cards are strong portraits before they're anything else: one figure, centred, holding something, framed by a border that tells you it matters. That structure is why a single photo is enough. Upload a portrait and it comes back redrawn — heavy black linework, gold on deep indigo, moons and stars and vines around the edge, a roman numeral at the top and your chosen name in small serif capitals along the bottom.
The format is the traditional one; the artwork is not copied from any published deck. Give it a name like The Oracle or The Keeper, or leave the field empty and let it name you.
