/* 记账猩官网 · 样式 v5
   视觉回到第三版的截图风格：居中标题、带投影的卡片、倾斜的真实界面和浮动数据卡。
   配色来自“配色定版”，另加几只可访问的文字色（对比度 ≥ 4.5:1）。
   长串内容（四步闭环、四类功能、模板）都做成左右切换的卡片。 */

/* ===== home-v5.css ===== */
/* 首页 v5：国内 B 端 + 飞书版式。只在 index-v5.html 引用，叠在 site.css / home-v2.css 之后。

   配色：一个主色相（品牌橙）的色阶 + 一个辅色（藏青）+ 中性灰，全部平涂。
   参考飞书 / 金蝶 / 钉钉的共同做法：
   - 主色只有一个色相，但分三档用：浅色调铺大面积（首屏、强调区底）、中间档做图标和标签、满色做按钮和关键数字
   - 区块底色按「白 → 浅灰 → 白 → 主色浅调」交替，制造节奏
   - 全页只有 1~2 块深色或满色整块，用来压住节奏（这里是：数据面板深色卡、收口橙色整块）
   - 辅色只在固定语义里出现：藏青 = 信任 / 安全 / 平台侧数据
