/* ============================================================
   Atelier Karia Guide —— 视觉皮肤
   设计语言取自本作官方美术（DESIGN-BRIEF.md）：
     · 底色 = Noctrem 地下夜国的深蓝紫 #0a1020 + 双层星云径向渐变
     · 主强调 = 官网 CSS 出现最多的深红 #ad3228
     · 描边与次要强调 = 金铜 #ce9e5f（游戏 UI 的金色描边）
     · 光晕 = 青荧 #4ad8d0（炼金发光圆环，只做光不做字）
     · 装饰母题 = 官方「细横线 + 末端小菱形」，菱形用 CSS 旋转方块实现
     · 字族 = 明朝体 Shippori Mincho（对应官网 "Shippori Mincho B1"）+ Zen Kaku Gothic New
   禁：硬阴影贴纸、粗墨线、纯黑底、直角粗边。
