/* ==================== 按钮（统一设计规范 v2）==================== */
/*
    设计原则：
    1. 三态一致：hover → 轻微上浮(+1px) + 阴影加深 + 颜色变暗/变亮；active → 按下复位 + 阴影变浅；focus-visible → 3px 聚焦环（无障碍）
    2. disabled → 灰化(opacity-50) + 禁手光标 + 禁用所有 transform 动画
    3. 尺寸：高度 40px / sm 32px / 圆角 md(10px) / sm(6px)
    4. 渐变主色 vs 纯色副按钮，视觉层次清晰
