Skeleton Loading Shimmer

Skeleton placeholder with a shimmer animation that sweeps across. Use while content is loading to prevent layout shift and give users a preview of the content structure.

.skeleton {
  background: #1c1c1f;
  border-radius: 8px;
  position: relative;
  overflow: hidden;
}
.skeleton::after {
  content: "";
  position: absolute;
  inset: 0;
  background: linear-gradient(90deg, transparent, rgba(255,255,255,0.05), transparent);
  animation: shimmer 1.5s infinite;
}
@keyframes shimmer {
  0% { transform: translateX(-100%); }
  100% { transform: translateX(100%); }
}
