미니멀리즘 스타일의 성 아우구스티누스 책 표지

A minimalist classical book cover in vertical format on a warm ivory or parchment background. At the top center, set the title in elegant large dark navy serif type across 2 lines: {argument name="title text" default="La Ciudad de Dios"}. Beneath it, centered with generous spacing, place a small gold phi symbol. In the upper-middle area, draw a delicate thin-line gold illustration of a fortified circular heavenly city with exactly 8 visible outer towers or gate structures, crenelated walls, and compact classical buildings inside, including a central dome. From the bottom center of this city, extend a soft vertical gold beam of light downward. In the lower-middle area, create thin dark navy line art of earthly classical ruins: the Roman Colosseum on the left, a large Greek or Roman temple with a triangular pediment and a long row of columns on the right, a broken fallen column in front, a small stone block near it, and an arched ruin structure spanning the lower left. Keep the composition symmetrical and airy, with lots of empty space, refined editorial balance, and subtle contrast between gold heavenly imagery and dark navy earthly architecture. At the bottom center, place the author name in matching dark navy serif type: {argument name="author name" default="San Agustín de Hipona"}. Clean premium literary design, sacred philosophy aesthetic, no extra text, no texture-heavy effects, no photographic elements.
