3/// 48co Custom Keyboard Extension
4/// Provides grammar-corrected typing + voice button on iOS
5///
6/// Built by Claude. Designed for humans.
7///
8/// How it works:
9/// 1. User enables 48co keyboard in iOS Settings → Keyboards
10/// 2. When typing, text is checked locally for grammar errors
11/// 3. Suggestions appear in the suggestion bar above the keyboard
12/// 4. Voice button triggers Whisper transcription
13/// 5. All processing happens on-device (no cloud needed)
