/* =========================================================================
   风之谷 · 界面样式（dist/style.css）
   -------------------------------------------------------------------------
   设计目标（docs/VISUAL_SPEC.md）：
     · 温暖绘本、风景为主角；菜单只在需要时出现。
     · 大字号、高可读：电脑关键目标 ≥14px、手机 ≥12px；触控命中区 ≥48px。
     · 手机横屏 HUD 不遮关键落点；触屏按钮避开底部系统区域（env(safe-area-inset)）。
     · 不使用草稿里的 8–12px 小字号与“无脚本占位”观感。
   结构：画布 #world 在最底层；HUD/目标/触屏在上；面板覆盖层最高。
   调色取 VISUAL_SPEC 固定色板，禁止另起霓虹高饱和界面色。
