房產帶看預約卡（建築線稿極簡風）

prompt

Create an elegant appointment card for a real estate agency, landscape 90x54mm, in a minimal architectural line-art style. Warm ivory background; across the top third, a continuous single-line drawing of a city skyline or house facade in thin {brand_color} strokes. Below, {agency_name} in a refined serif, then {agent_name} and {agent_phone} in small caps. The right side holds blank ruled fields labelled Date, Time and Address for handwritten viewing details, with a small key icon as a divider. Mention the specialisation in {property_area} as a subtle one-line footer. Lots of white space, premium uncoated-paper texture, flat print-ready design, no photographs.
