Vintage Macau Map Poster

Create a refined vintage line-art travel poster on warm aged parchment paper, centered on a delicate hand-drawn outline map of {argument name="region" default="Macau, China"}. Use thin sepia ink lines with subtle watercolor washes and lots of empty beige space. Inside the map, place exactly 6 illustrated landmark elements: 1 ornate Baroque church facade near the top with small green and red trees beside it, 1 tall Macau Tower in the middle rising from calm water with low green hills behind it, 1 blue-and-white porcelain teacup in the lower middle-left, 1 flowing black-and-white Portuguese wave mosaic pavement pattern curving across the lower middle-right, 1 pink lotus flower with a green lotus leaf near the bottom, and 1 long narrow bridge extending from the right side of the map. Add a few tiny detached island shapes around the main map outline. Keep the composition elegant, minimal, museum-poster-like, with fine architectural detail, faint speckles, and soft muted colors only inside the illustrations. At the bottom center, add the Chinese title {argument name="main title" default="中国澳门"} in widely spaced black serif-style characters, and beneath it the smaller subtitle {argument name="subtitle" default="内部的小世界"}. No people, no modern graphic effects, no border, no watermark.
