/**
 * style.css — 杯友社设计系统（Design System）
 * ----------------------------------------------------------------------------
 * 级联层顺序（优先级 低 → 高）：reset < tokens < themes < base < components < utilities
 *   - tokens 定义设计变量；themes 在不同时机覆写变量（明暗主题），二者都在组件之前，
 *     组件只消费 var()，从而做到"换主题=换变量，不改任何选择器"。
 *   - 自定义属性的胜负由层优先级决定：themes 层高于 tokens 层，所以深色变量稳定生效。
 *
 * 设计约束：
 *  - 移动优先（参考原型 390×844），同时适配桌面端（max-width 容器 + 双栏 sidebar）。
 *  - 主色明亮玫红 --c-primary，中性灰背景，文本对比度 ≥ 4.5:1（无障碍）。
 *  - 所有尺寸基于 8px 基线网格（--sp-*）。
 *  - 保留 :focus-visible 焦点样式（键盘导航可见）。
