/* ============================================================================
 * components.css —— SPA 化后聚合的各页面专属样式（原分散在各子页 head <style>）
 * ----------------------------------------------------------------------------
 * 由 index.html 统一引入；全局通用类（.page/.data-table/.btn/.modal 等）仍在 theme.css。
 *
 * ⚠️ 作用域纪律（合并成单文档后新增的硬性要求）：
 *   原来每个子页是独立 HTML，同名类（.field/.form-card/.toolbar/.muted…）互不干扰；
 *   合并到一个文档后，若继续写成全局选择器，后写的会覆盖先写的，甚至污染控制台。
 *   因此除「跨页共用」区块外，所有页面专属样式必须挂在页面根类下：
 *     .pg-logs / .pg-accounts / .pg-license / .pg-settings
 *     .pg-product / .pg-users / .pg-music / .pg-regcode
 *   这些根类由 index.js 中对应视图组件的根 div 提供。
