   狐面屋 Kitsune Play —— 視覺（第三版，2026-09-18）
   ---------------------------------------------------------------------------
   世界觀是「祭典的夜晚」：靛藍的夜色、燈籠的暖光、狐火的青白。
   參考座標是**遊戲主機商店的首頁**（主視覺、縮圖列、有編號的收藏卡），
   不是娛樂城大廳。

   第三版跟第二版的差別，一句話：少一點框、多一點材質與節奏。

     · 段落標題有了「拉丁字 kicker + 中文標題 + 一條延伸的線」的固定節奏
     · 主視覺底下是十張縮圖（以前是十顆點，看不出哪顆是哪款）
     · 卡片有圖鑑編號（No.01 … No.10），十款是一套收藏，不是十張廣告
     · 介紹頁四個章節有編號，結尾是用該款自己的場景與角色做的橫幅
     · 夜祭的遠景（山、鳥居、燈籠）從「固定在視窗底部」搬進頁尾 ——
       以前它會透在錢包表格與條款內文後面
     · 全站鋪一層很淡的和紙顆粒；橫幅底下鋪七宝紋，都只有幾個百分點

   ⚠ 這份樣式刻意不提供的東西，每一項都是為了不讓它看起來像賭場：

     · 沒有金色漸層、沒有黑底金字（那是賭場的預設配色）
     · 沒有 $ / NT$ 的樣式 —— 錢包裡是狐幣，用幣的圖示不用貨幣符號
     · 沒有跳動、閃爍、發光的金額數字
     · 沒有「限時」倒數條、沒有紅色促銷角標
     · 朱紅只用在點綴（鳥居、章節印記、focus），不做大面積

   「質感」在這裡的意思是：多層但很淡的陰影、1px 的亮邊、玻璃質感的面板、
   短而有加速度的動效、留白、字距。不是更多光暈。

   ⚠ backdrop-filter 只用在少數幾個大面積的元件（頁首、主視覺底下的兩條
     導覽列、箭頭、玻璃按鈕）。封面上的小籤、標題旁的小標一律用半透明底色 ——
     一頁裡幾十個毛玻璃元件會讓手機的合成器跟不上（2026-09-18 在平板寬度
     實際看到畫面停住不重繪）。

   固定深色。這不是「還沒做淺色模式」，是夜祭本來就在晚上。

   ⚠⚠ 頁面那側（web/*.ts）**不能**寫 style="…"：全站 CSP 是 style-src 'self'，
       HTML 的 style 屬性會被瀏覽器丟掉，而且不會有任何錯誤提示。
       CSS 裡的 data: 圖（顆粒、七宝紋）走的是 img-src，那一條允許 data:。
