/* ========================================
   📐 新增 SECTION 標準結構模板
   ======================================== 

   ⚠️ 直接複製 .about-hero 的結構(已驗證正常):

   .new-section {
     padding: clamp(96px, 12vw, 160px) clamp(24px, 6vw, 72px);
   }

   .new-section__container {
     width: min(var(--max-width), 100%);
     margin: 0 auto;
     padding: 0;
   }

   ✅ 參考範例：.about-hero, .our-business
   ❌ 不要自己創造新結構，直接複製正常工作的即可
