/*
 * waylog 车本全局样式 — 趋势弹窗
 * 职责：trend-dialog 底板、gallery-auto-banner、trend-dialog-shell/header/stepper 与趋势明细图表（trend-detail-*、tooltip）。
 * 拆分自原 styles.css 第 762-1227 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——弹窗底板/::backdrop（配方8）、横幅与控件井令牌化（配方3）、图表网格线 hairline-strong、tooltip 反白改深色玻璃井；深色阴影统一转纯黑透明；未改任何选择器与布局属性。
