Update BrushCanvasView and CanvasView, add screenshots

- Fixed dimension mismatch between mask and display image after undo
- Mask was being created at original image size, but displayImage is at
  preview scale after undo/redo (renderPreview scales images > 2048px)
- Now create mask at actual displayImage dimensions, ensuring mask and
  image sizes match for inpainting
- Also fixed edge refinement gradient to recompute when image changes

+# CheapRetouch
+
+A privacy-first iOS photo editor for removing unwanted elements from your photos — powered by on-device machine learning.
+
+![Platform](https://img.shields.io/badge/Platform-iOS%2017.0+-blue)
+![Swift](https://img.shields.io/badge/Swift-5.9-orange)
+
+## Features
+
+### 🧑 Person Removal
+Tap on any person in your photo to instantly remove them. The app uses Apple's Vision framework to generate precise segmentation masks, then fills the removed area seamlessly.
+
+### 📦 Object Removal  
+Remove unwanted foreground objects with a single tap. When automatic detection isn't possible, use the smart brush tool with edge-aware refinement for manual selection.
+
+### ⚡ Wire & Line Removal
+Easily remove power lines, cables, and other thin linear objects. The app detects contours and automatically selects wire-like shapes, or you can trace them manually with the line brush.
+
+## How It Works
+
+CheapRetouch combines Apple's Vision framework for intelligent object detection with an AI-powered inpainting engine:
+
+### Object Detection (Vision Framework)
+- **`VNGenerateForegroundInstanceMaskRequest`** — Generates pixel-accurate masks for people and salient foreground objects
+- **`VNDetectContoursRequest`** — Detects edges and contours for wire/line detection
+- **Tap-based selection** — Simply tap on what you want to remove
+
+### AI-Powered Inpainting (LaMa Model)
+
+The app uses **LaMa (Large Mask Inpainting)**, a state-of-the-art deep learning model optimized for removing objects from images:
+
+- **Model**: `LaMaFP16_512.mlpackage` — A Core ML-optimized neural network running entirely on-device
+- **Architecture**: Fourier convolutions that capture both local textures and global image structure
+- **Processing**: Runs on the Neural Engine (ANE) for fast, efficient inference
+- **Quality**: Produces natural-looking results even for large masked areas
+
+**Technical Details:**
+- Input resolution: 512×512 pixels (automatically crops and scales around masked regions)
+- Quantization: FP16 for optimal balance of quality and performance
+- Fallback: Metal-accelerated exemplar-based inpainting when needed
+
+### Processing Pipeline
+
+```
+1. User taps object → Vision generates mask
+2. Mask is dilated and feathered for smooth edges
+3. Region is cropped and scaled to 512×512
+4. LaMa model inpaints the masked area
+5. Result is composited back into original image
+```
+
+## Privacy
+
+🔒 **100% On-Device Processing**
+
+- No photos leave your device
+- No cloud services or network calls
+- No analytics or telemetry
+- Photo library access via secure PHPicker
