/* =========================================================
   大武山成年禮｜全站質感疊加層 v1（2026-10-15）
   定位：疊在 tawu-refine-v1.css 之後，只做「細節的一致性與動態的節奏」，不動文字內容。
   原則：克制、溫潤；一切動態都只用 opacity／transform，並尊重「減少動態」設定。
   內容：圓角三級制、標題進場、段落錯落淡入、
         卡片與按鈕互動、FAQ 展開、跨頁淡入轉場、焦點樣式、紙面頁首的等高線底紋。
   ========================================================= */
