/* ============================================================
   wedding-starlit｜一場星空夜宴
   概念：喜帖＝為你留了位子的星空夜宴。全站唯一深色模板。
   - 開場：一片夜幕，賓客親手向上拉開（純 CSS 跟手、可點跳過）
   - 深夜藍底 × 香檳金 accent × 米白正文；星空鋪在內容底下
   - Gallery 是懸星燈箱：照片像掛在星圖上的一列發光燈箱
   - 終章「連星成名」：按住夜空把星星連成賓客名字的星座
   動態語彙：星點顯影 ＋ 燈箱點燈 ＋ 螢火蟲 ＋ 星軌劃過
   色彩與間距 token 覆寫自 /shared/base.css。
   深色注意：--warn 必須調亮（base 的磚紅在夜藍底不可讀）、
   focus ring 一律香檳色、accent 自訂由 WKSTYLE.apply(C,{dark:true})
   走深色 clamp（shared/style.js DARK_PAPERS）。
