   main.css — 台南市第二區居家托育服務中心
   ------------------------------------------------------------
   建立：2026-08-26
   取代：style.css(80KB) + css/responsive.css(37KB) + css/shortcodes.css
        + css/layerslider.css + css/prettyPhoto.css

   重寫原因：
   1. 舊版 style.css 引用 39 個版型圖片，這些圖檔全部不存在 → 破圖
      本檔完全不依賴任何背景圖，所有裝飾以純 CSS 繪製
   2. 舊版排版以 float + 固定寬度為主，手機幾乎不能看
      本檔改用 Flexbox / Grid，並用 clamp() 做流體字級
   3. 舊版指定 "Microsoft Yahei"（簡體中文字型），改為繁體中文字型堆疊

   配色沿用原版型：teal #008c99 / 金 #df9b00 / 橘 #cf571b
