+<summary><b>LCSnackBarView</b> — in-app notification banner</summary>
+
+A chainable banner shown from the top or bottom of a controller. Configure with
+`configure(...)` calls, then `present()`.
+
+### `init(style: LCSnackBarViewType = .default, orientation: LCSnackBarOrientation = .top, delegate: LCSnackBarViewDelegate? = nil)`
+
+### Enums
+- `LCSnackBarViewType` — `.default` (rectangular) / `.rounded`
+- `LCSnackBarOrientation` — `.top` / `.bottom`
+- `LCSnackBarTimer: CGFloat` — `.infinity` (0, manual dismiss), `.minimum` (2s), `.medium` (5s), `.maximum` (10s)
+
+### Configuration (each returns `Self`)
+| Method | Sets |
+|---|---|
+| `configure(text: String)` | the message |
+| `configure(textColor: UIColor)` | text colour |
+| `configure(textFont: UIFont, alignment: NSTextAlignment = .center)` | font + alignment |
+| `configure(backgroundColor: UIColor)` | banner background |
+| `configure(exibition timer: LCSnackBarTimer)` | how long it stays |
+| `configure(imageIconBefore icon: UIImageView, withTintColor: UIColor? = nil)` | leading icon |
+
+### `func present(completion: (() -> Void)? = nil)`
+Show on the top-most view controller.
+
+### `weak var delegate: LCSnackBarViewDelegate?`
+`snackbar(didStartExibition:)`, `snackbar(didTouchOn:)`, `snackbar(didEndExibition:)` — all optional.
+
+### Full example
+
+```swift
+LCSnackBarView(style: .rounded, orientation: .bottom)
+    .configure(text: "Profile saved")
+    .configure(backgroundColor: .systemGreen)
+    .configure(exibition: .minimum)
+    .present()
+```

+<summary><b>ImagePickerController</b> — camera / photo-library picker with permissions</summary>
+
+Wraps `UIImagePickerController`, handling camera & photo-library authorization
+(including the "go to Settings" path) and presenting a source-choice alert.
+
+### `init()`
+### `weak var delegate: ImagePickerControllerDelegate?`
+### `var isEditable: Bool` — allow in-picker cropping (default `false`)
+### `func openImagePicker()`
+Check permissions, then present the camera/library choice.
+
+### `protocol ImagePickerControllerDelegate: AnyObject`
+`imagePicker(didSelect image: UIImage?)` — the picked (or edited) image, or `nil` on cancel/failure.
+
+```swift
+let picker = ImagePickerController()
+picker.delegate = self
+picker.isEditable = true
+present(picker, animated: false) { picker.openImagePicker() }
+
+// ImagePickerControllerDelegate
+func imagePicker(didSelect image: UIImage?) {
+    avatarView.image = image
+}
+```

+<summary><b>ImageZoomController</b> — full-screen pinch-zoom / pan viewer</summary>
+
+### `init(_ withImage: UIImage)`
+### `var minimumZoomScale: CGFloat` (default `1.0`) / `var maximumZoomScale: CGFloat` (default `6.0`)
+### `var addGestureToDismiss: Bool` (default `true`) — drag down to close
+### `weak var delegate: ImageZoomControllerDelegate?`
+### `func present(completion: (() -> Void)? = nil)` / `func dismiss(completion: (() -> Void)? = nil)`
+Present from / dismiss to the top-most controller.
+
+### `@objc protocol ImageZoomControllerDelegate`
+`imageZoomController(controller:didZoom:)`, `imageZoomController(controller:didClose:)` — both optional.
+
+```swift
+let viewer = ImageZoomController(photo)
+viewer.maximumZoomScale = 4
+viewer.present()
+```

+<summary><b>GifHelper</b> — animated GIF loading</summary>
+
+### `UIImageView.loadGif(name: String)` / `UIImageView.loadGif(asset: String)` *(iOS 9+)*
+Decode a bundled `.gif` (or an asset-catalog data set) off the main thread and
+assign the resulting animated `UIImage`.
+
+```swift
+bannerView.loadGif(name: "loading")        // loading.gif in the bundle
+bannerView.loadGif(asset: "confetti")      // NSDataAsset "confetti"
+```
+
+### `UIImage.gif(data: Data) -> UIImage?` / `gif(url: String) -> UIImage?` / `gif(name: String) -> UIImage?` / `gif(asset: String) -> UIImage?`
+Build an animated `UIImage` from GIF bytes / a URL string / a bundled file / an
+asset-catalog entry. Frame delays are honoured (via the GCD of per-frame delays).
+
+```swift
+let spinner = UIImage.gif(name: "spinner")
+imageView.image = spinner
+```
