/* =====================================================
 * idindoo 笔记助手 — 设计系统 v12
 *
 * 灵感:Apple 官网 (mac-studio 页面) — 深度学习
 * https://www.apple.com.cn/shop/buy-mac/mac-studio
 *
 * Apple 风格提炼的 8 个核心点:
 *   1. 大圆角(产品图 18-24px,卡片 18-20px,按钮 980px pill)
 *   2. 半透明顶栏 + backdrop-filter saturate(180%) blur(20px)
 *   3. 大量留白(section 间距 32-80px,卡片 padding 24-40px)
 *   4. 大字号(标题 32-48px,正文 17px,小字 14px)
 *   5. SF Pro 字体栈 + 数字 tabular-nums + 字重 400-600
 *   6. Apple 蓝 #0071e3 作为"行动色"(新增),小红书红保留作品牌色
 *   7. 极细 1px 边(rgba(0,0,0,0.08) 浅 / rgba(255,255,255,0.12) 暗)
 *   8. 极轻 hover(只 background 微变,无 transform 无 shadow)
 *
 * 实战取舍:
 *   - workspace 内部仍保持"工具感"(白底 + 1px 边),不搞全黑底
 *   - 顶栏 / hero 区域用 Apple 风(留白 + pill 按钮 + 大标题)
 *   - 卡片用大圆角 18px,告别 v11 的 6px 小圆角
