/**
 * CaseShow 通用插件样式 (caseshow.css)
 * ------------------------------------------------------------------
 * 主题无关：所有外观值由 CSS 变量驱动，变量通过后台「外观设置」注入
 *   --cs-primary 主色 / --cs-accent 辅色(精选角标)
 *   --cs-bg 区块底色 / --cs-radius 圆角 / --cs-cols 桌面列数
 * 每个变量都带 fallback，未注入设置时也有合理默认，换主题不裸奔。
 * 主题若要覆盖，只需在更高优先级样式表里重写 .cs-* 规则即可。
