/* ============================================================
   atlas.css — THE ATLAS 擎海「Harbour」Skin
   ------------------------------------------------------------
   用法：site.atlas.json project.skin = "atlas"
   → base.html 於 themes.css 之後自動載入本檔，並於 <html> 加
     data-skin="atlas-official"。所有規則一律 html[data-skin="atlas-official"] 開頭，
     保證覆蓋 forge.css/themes.css，亦唔會影響冇用 skin 嘅網站。

   設計語言：Harbour（深海藍 × 海水青 × 淡金 × 海霧白）
   - 底 #F5F9FA 海霧白、白卡、1px 髮絲線 #D8E6EC
   - Hero 用全幅航拍／海景相 + 深藍遮罩，白字
   - 標題用 serif display（Playfair Display + Noto Serif TC）
   - 主按鈕深海藍 #0D3349；金 #4FA3D1 只做 accent（rule/eyebrow/hover）
   - 線條圖示 1.5px stroke（build.js GRID_ICONS）
   - Footer 深夜藍 #06293B
