 * 颜色、圆角、列数等可配置项全部由模板注入的 CSS 变量驱动（见 library/Data::themeStyle()），

 * 变量清单：
 *   --hp-primary / --hp-primary-rgb  主色与其中间色（拼 rgba 用，避免 color-mix）
 *   --hp-radius / --hp-cols          圆角、卡片列数
 *   --hp-bg / --hp-bg-soft           页面底色
 *   --hp-surface / --hp-surface-2    卡片/输入框底色
 *   --hp-text / --hp-muted           正文与次要文字
 *   --hp-border / --hp-shadow        描边与阴影
 *   --hp-chip                        标签底色
 *   --hp-hero-text / --hp-blur       标题区文字色、玻璃主题的模糊半径
