zhangxiang 045c5095c1 fix(build): 改 darkMode 为 variant 模式让 Tailwind dark: 变体按 data-theme='dark' 触发
- tailwind.config.js darkMode 从 'class' 改为 ['variant', '[data-theme="dark"] &']
- 'class' 模式匹配 .dark class,但站点用 html[data-theme='dark'] 属性,导致 dark: 变体全局失效
- variant 模式让 dark:bg-foo 类生成 [data-theme="dark"] .dark\:bg-foo 选择器
- 验证:临时加 dark:bg-blue-500 → CSS 含正确选择器;运行时浅色 bg=white、深色 bg=rgb(59,130,246)

回归测试脚本:
- darkmode-selector-verify.mjs:合成探针验证 utility 生效
- home-cta-verify.mjs:定位 home 本地简化 CTASection 实际渲染(之前误判为'不渲染')

诚实标注:
- 全站 grep dark: utility class 仅发现 cta-button.tsx 2 处,但均为 TS 对象 key(非 utility),故 dark: 失效问题无直接破坏
- 修复属'基础设施补全':未来添加 dark: 工具类即按 data-theme='dark' 自动生效

home-content-v15.tsx 的 CTASection(line 978-998)是**文件本地简化版**
(仅标题 + CTAButton,无 BrandStamp),与 src/components/sections/cta-section.tsx
(含 BrandStamp「值得信赖」)是不同组件。前者实际渲染,后者无路由使用(待用资产)。
本修复不涉及 CTASection 渲染路径。

验证:
- type-check 0 error
- lint 0 error
- 编译产物含 [data-theme="dark"] .dark\:bg-blue-500 选择器
- 运行时合成探针 PASS(浅色 white / 深色 blue)
