/* =============================================================
   style.css — 推廣體驗版視覺（CR-049；階段 3 依提案版重做）
   =============================================================
   來源＝`外來資源/攤位版體驗提案`（團隊會議用的視覺提案，git 忽略、不入版控）。
   階段 2 的骨架版把每一頁都垂直置中、只用單一純色底；階段 3 改為提案版的做法：
     1. 每個節點各自的 radial-gradient 底，準備頁用滿版照片 ＋ 由上到下的漸層遮罩。
     2. 版面分「上半（置中偏上）／下半（margin-top:auto 貼底）」兩段，不再整頁置中。
     3. 按鈕為寬版 pill、字距 .2em；主按鈕米棕、次按鈕描線。
     4. N5 的收藏卡預覽是完整迷你卡（.rc.mini）。
   ⚠ 無任何 CDN、無外部字型；結果圖字型由 renderer 自行載入（見 js/fonts.js）。
   ⚠ N4 的 `.step`／`.mandala` 動畫時長與 `views.js` 的 `--d`、`main.js` 的 CTA 延遲**三處連動**：
     揭示全部結束後要留約 1.2 秒停留，「我看見了」才出現（提案原文＝「全部出現後再停約 3 秒」）。
     餘裕由 `tests/promo/frontend-static.test.mjs` 現場算出並守住 ⇒ **改任一處都要跑測試**。
