// Example data source for the `home` feature. This is intentionally dependency-light
// (no Firebase / no Room coupling) so the scaffold builds in every feature combination.
//
// Real apps swap this for a Firestore/Ktor source and add a Room cache (see data/local).
// The Clean Architecture seam is the ItemRepository interface in the domain layer.
//
// The repository is the ONLY exception-translation point: I/O runs inside
// suspendRunCatching (data/AppResultCatching.kt), which maps infrastructure exceptions
// to typed DomainError values and ALWAYS rethrows CancellationException. Pass a mapError
// lambda to classify your real source's exceptions (IOException -> Network, etc).
