/**
 * visual-templates.css — 投标书视觉模板覆盖层
 *
 * 职责：
 *   - 为 .content-view-container 上挂载的 [data-template="<id>"] 提供整页配色覆盖。
 *   - 仅作用域到指定 data-template 选择器，未挂载模板时正文模式表现完全不变。
 *   - 与 visual-templates.js 中的 cssVars 字段对齐：JS 未来若需要按模板临时换色，可直接覆盖 CSS 变量。
 *
 * 扩展方式：
 *   - 新增模板时，复制下方 [data-template="blue-orange"] 块改 id 与配色即可。
 *   - 标题横条/表格首列等"模板独有的视觉装饰"集中写在这里，bid-generator.css 不动。
