v0.3.0

Added

• LoadState<T, F> — a Loading/Success/Failure sealed state, plus a
  matching SkeletonContainer(state, onFailure, content) overload for it.
  Unlike the isFailure/dataOrNull overload, state's shape is fixed
  to LoadState in exchange for onFailure receiving a concretely typed
  failure payload with no cast required. Loading isn't special-cased by
  the overload — it's whatever state isn't Success or Failure, so
  the shimmer shows automatically with no extra branching needed.
  Demonstrated in the sample app via LoadStatePostCard.

Changed

• SkeletonContainer(state, dataOrNull, isFailure, onFailure, content)'s
  onFailure slot is now @Composable (S) -> Unit, receiving the failure
  state directly instead of requiring callers to re-derive it from the
  outer state.

v0.2.0

Added

• SkeletonContainer(state, dataOrNull, isFailure, onFailure, content) — a
  state-driven overload for sealed/state-based loading (e.g. a
  Loading/Success/Failure state), deriving loading and a typed
  success payload from the caller's own state instead of a plain
  Boolean, with a dedicated onFailure slot. Demonstrated in the sample
  app via StateDrivenPostCard.

v0.1.0

Added

• SkeletonContainer(loading) — hosts one shared shimmer animation per subtree.
• Modifier.skeleton(shape) — draws a placeholder matching the element's own
  measured bounds while loading, crossfading to real content when it's done.
  Supports SkeletonShape.Auto (default), SkeletonShape.Circle, and
  SkeletonShape.RoundedCorner(radius).
• SkeletonDefaults — corner radius, MaterialTheme-derived shimmer colors,
  and crossfade animation defaults, all overridable per SkeletonContainer.
• Android, iOS, and Desktop (JVM) targets.
