/* ==========================================================================
   高雄租車優勢版塊  .ra-adv   v1.0（點擊卡片揭示文案・純 CSS）
   適用：欣興高雄租車（SoberCMS / themes/zy001）
   放置位置：themes/zy001/css/rent_adv.css（以 <link> 引入）
   設計依據（皆取自站上 css.css / rent_flow.css）：
     · 區塊標題沿用 .indextitle（News 最新消息 / Process 高雄租車詳細流程）同一套樣式
     · 主色沿用站上品牌深藍 #171c61、輔色 #3f93bf、淺藍底 #f3f8fc
     · 直角、細邊框、無漸層、無重陰影（站上為平面設計語彙）
     · 取代原本 5 組 .iservA 交錯圖文列，點卡片看文案、再點一次返回圖片
