/* ==========================================================================
   Pixel Chili 4.0 —— "客家围屋 / HAKKA PIXEL" 版式重构
   --------------------------------------------------------------------------
   设计约定：
   1) 视觉语言：岭南客家（梅州/赣南）——围龙屋、半月池、石牌坊、大榕树、
      红灯笼、青瓦白墙；**白天**、写实、明亮，彻底去掉赛博/蒸汽波元素；
   2) 配色取自围屋实拍：青瓦 #5A5245、白粉墙 #E7DFCC、夯土 #C9AC83、
      红砖 #A56C4E、石 #ABA69A、朱漆门 #B3362C、匾额金 #C9A227、
      半月池 #5A8E94、远山 #6E9480；
   3) 字体：Fusion Pixel 12px（OFL，标题/UI，整数倍才清晰）+ Zpix（正文）；
   4) 一切造型用硬边像素与实色块，不用渐变辉光、不用毛玻璃；
   5) 动效舒缓：云影飘、白鹭滑、灯笼轻摇，遵循 prefers-reduced-motion。
