/**
 * CSS动画性能优化
 * 
 * ⚠️  已优化: 移除全局 will-change,改为按需使用
 * 
 * 注意事项:
 * 1. will-change 只在动画执行期间添加
 * 2. 动画结束后必须移除,释放内存
 * 3. 优先使用 transform 和 opacity (GPU 加速)
 * 4. 避免对大量元素使用 will-change

/*
优化建议:
1. 优先使用 transform 和 opacity 进行动画 (GPU加速)
2. 避免对 width, height, top, left 进行动画 (触发重排)
3. 对于大量动画,考虑使用 CSS transform: translateZ(0) 强制GPU加速
4. 使用 requestAnimationFrame 进行动画而非 setInterval
5. 在动画结束后移除 will-change 属性以释放内存
*/

/* ═════════════════════════════════════════════════════════
   💡 GPU 加速优化
   ═════════════════════════════════════════════════════════

强制 GPU 加速 (慎用,仅用于关键动画):
.gpu-accelerated {
  transform: translateZ(0);
  will-change: transform;
}

.backface-hidden {
  backface-visibility: hidden;
  perspective: 1000px;
}

/* Trust Bar CSS 已迁移至 styles.css */

📝 示例: 动态添加 will-change 的 JavaScript 函数
/*
function startAnimation(element) {
  element.style.willChange = 'transform, opacity';
}

function endAnimation(element) {
  element.style.willChange = 'auto';
}
*/
