// Mirrors the server's Page[T] envelope used by paged endpoints
|
|
// (/api/search, /api/library/artists, /api/library/albums,
|
|
// /api/likes/*). Class is named `Paged<T>` rather than `Page<T>`
|
|
// to avoid ambiguous imports with Flutter Material's Navigator-2.0
|
|
// `Page` class.
|
|
//
|
|
// Wire shape from internal/api/types.go Page[T]:
|
|
// { items: T[], total: int, limit: int, offset: int }
|
|
//
|
|
// Dart generics can't auto-infer T from JSON, so callers pass an
|
|
// itemFromJson function alongside the raw map. Parse logic stays in
|
|
// each entity's own fromJson; this class only handles the envelope.
