- add translation support for Cantonese using traditional Chinese (Mandarin). Works fine as a workaround until iOS supports Cantonese translations natively

• History: Save Hanzi entries and revisit them anytime. Tap to expand, switch between original and transliterated text, and play audio. Swipe to delete or clear all. • Audio playback: Listen to any Hanzi text in Mandarin or Cantonese pronunciation. • Save from the Text tab or long-press an OCR result to add it to your History. Plus performance improvements and refinements throughout the app.

- Added Cantonese support: - New `JyutpingDictionary` backed by a bundled `cantonese.json` generated from the Unihan `kCantonese` field. - `TextProcessor` gains a `.cantonese` mode that romanizes Hanzi to Jyutping. - Settings expose a "Cantonese" Chinese variant; text mode swaps the "Pinyin" header for "Jyutping", disables the translation language picker and hides the translation section since the Apple Translation API does not support Cantonese. - Added a setting to dismiss the keyboard automatically when typing Hanzi on the home tab. - Camera: configure the `AVCaptureSession` once at startup and only start/stop it on tab switch, removing the visible reconfiguration delay when returning to the camera tab.

- Modernized the SwiftUI codebase to iOS 17+ patterns: - Migrated state from `ObservableObject` / `@Published` / `@StateObject` to `@Observable` + `@State` + `@Environment`. - Replaced `NavigationView` with `NavigationStack` and switched the tab bar to the iOS 17 `Tab` API with an enum-typed selection. - Replaced `MagnificationGesture`, `foregroundColor`, `cornerRadius` and `UIImpactFeedbackGenerator` with `MagnifyGesture`, `foregroundStyle`, `clipShape(.rect(...))` and `sensoryFeedback`. - Replaced Combine `debounce` and `DispatchQueue.asyncAfter` with cancellable `Task` + `Task.sleep`. - Camera view polish: - Split into dedicated `CameraPermissionView`, `CameraLiveView`, `RecognizedTextOverlay` and `CopyToast` views. - Added a `ContentUnavailableView`-based permission screen with a deep link into Settings. - Text view polish: - Replaced the read-only `TextEditor` with a `Text`-based `ReadOnlyTextBox` and switched the Hanzi input to `TextField(axis: .vertical)`. - Added a shared `AppDesign` enum with spacing, corner radii, animation durations and tap target constants used across views. - Fixed OCR overlays on gallery and captured photos rendering at the wrong size and position by mapping Vision's normalized box onto the displayed image's aspect-fit rect and passing the image orientation to the Vision request.

- Camera controls: Pinch-to-zoom and 1x/2x/5x preset buttons in the camera view, with automatic lens switching on devices with multiple back cameras (triple/dual)

Released on 03/01/2026 - Issue 10: Do not strip non-Hanzi characters from a sentence that contains Hanzi. For instance `我在NASA工作. 现在是5点.` caused converted text to be just `wǒ zài gōng zuò. xiàn zài shì diǎn.` instead of `wǒ zài NASA gōng zuò. xiàn zài shì 5 diǎn`. - Issue 9: Added tab to file issues from within the app.

- Issue 2: Fixed camera not auto-focusing when moving closer to text. - Issue 4: Better feedback for copying text to the clipboard from text overlays.

Fixed OCR box position in live mode
