/* ==========================================================================
   世界速報站 — Design System
   風格定位：編輯／雜誌感的世界新聞週報站，走「數位報刊」路線，不是科技產品
   登陸頁。淺色是冷調石灰紙感（老地圖/羊皮紙的灰調，不是咖啡廳暖米白），
   深色是墨黑報紙感（偏冷炭灰，不是霓虹深空）。強調色是黃銅金／磚紅／深青，
   刻意避開「暖米白+赤陶橘」這種常見AI生成配色公式——黃銅金呼應老地球儀的
   金屬底座與經緯儀，深青呼應海圖上的水域，磚紅只留給天災警示用，不當主色。
   標題用襯線字（Noto Serif TC）撐視覺重量，內文與介面用 Noto Sans TC，
   數字／時間戳用 Space Grotesk 等寬數字。卡片用細線分隔＋淡陰影，不用玻璃感
   發光卡片；背景是極淡的經緯線＋地球儀剪影，不用發光模糊光球。
