/*
 * waylog 车本全局样式 — 总览支出图表
 * 职责：expense-chart、daily-expense/daily-flow 柱状图、daily-cost-average、expense-day/category 明细与 expense-chart-empty。
 * 拆分自原 styles.css 第 1228-2032 行：规则内容零改动，仅按行切分；级联顺序 = 本文件在 index.html 中的链接顺序。
 * EV 暗色主题适配：按 docs/reskin-guide.md 原位换肤——分段选择胶囊化+accent 选中态（配方4）、零轴/分隔线/发丝环令牌化（hairline/hairline-strong）、明细井改 surface-control、hover 改提亮；柱体类目色变量保持不变；修复未定义的 --focus 焦点环。
