/*
 * AETHER Design System — Font Faces
 *
 * 字体架构：
 *   Inter          — 主字体（展示层 + 功能层），300/400/500/600/700
 *   JetBrains Mono — 等宽字体（数据层），400
 *
 * 格式策略（对标 Claude/Anthropic 设计系统）：
 *   - 仅 woff2，现代浏览器均支持
 *   - font-display: swap 防止 FOIT
 *   - unicode-range 限定 Latin 子集，CJK 自动回退系统字体
 *   - 相对路径，CSS 与 woff2 同目录
