/*
 * 交錯的延遲刻意不寫在 CSS 裡，由 site.js 依「實際進場的順序」直接設
 * 行內樣式，進場跑完再清掉。
 *
 * 原本是 .reveal:nth-child(2..5) 各給 100~400ms，有兩個問題：
 *
 * 1. nth-child 數的是 DOM 順序，不是版面上的第幾個。產品列表三欄時
 *    只有前五個有延遲，於是第二排變成「第 6 張最先出現、然後才是
 *    第 4、5 張」。欄數在三個斷點還會變（4/3 → 2 → 1），要寫對就得
 *    每個 grid、每個斷點各來一組規則，跟 grid-template-columns 綁死。
 *
 * 2. transition-delay 是長寫法、權重 (0,2,0)，會蓋過元素自己那條
 *    transition 縮寫裡隱含的 delay: 0s。而 .reveal 常常就掛在卡片本身
 *    （<a class="prod-card reveal">），結果那些卡片的 hover 也要先等
 *    300／400ms 才開始動 —— 看起來就是「頓頓的」。
 *
 * 行內樣式權重最高、又能精準清除，兩個問題一起消失。
