-# PNGer Development & Technical Instructions
-
-## Project Overview
-
-PNGer is a single-container web application for PNG editing and resizing, designed for deployment on Unraid with Gitea version control. It features a modern Svelte frontend and a high-performance Node.js/Sharp backend.
-
-## Technical Architecture
-
-### Architecture Overview
-
-PNGer uses a multi-layered architecture designed for responsiveness and efficiency:
-
-```mermaid
-graph TD
-    A[User Browser] --> B[Svelte Frontend]
-    B --> C[Canvas API (Live Preview)]
-    B --> D[Express API (Backend)]
-    D --> E[Sharp Image Library]
-    D --> F[Runtime Environment (Docker)]
-```
-
-### Backend (Express + Sharp)
-
-The backend is built with Node.js and TypeScript, using Express for the API and Sharp for high-performance image processing.
-
-**Key Endpoints:**
-- `POST /api/transform` - Transform image (resize, crop, compress, convert)
-- `GET /api/health` - Health check
-
-**Key Dependencies:**
-- `sharp`: High-performance image processing (handles resizing, cropping, and format conversion).
-- `multer`: Middleware for handling `multipart/form-data`, used for file uploads.
-- `express`: Web framework for the API.
-
-### Frontend (Svelte + Vite)
-
-The frontend is a reactive Svelte application that prioritizes real-time feedback and UX.
-
-**Core Components & Modules:**
-- `App.svelte`: Main application container managing state and UI.
-- `lib/api.ts`: API client for backend communication.
-- `lib/preview.ts`: Client-side preview logic using the Canvas API for instant feedback.
-- `lib/theme.ts`: Dark/light theme management with persistent storage.
-- `lib/presets.ts`: Configuration for smart image presets.
-
-### Design System (Dark/Light Modes)
-
-The UI uses a modern design system with CSS custom properties for theming:
-- **Light Mode**: Clean white background with dark gold (`#b8860b`) accents.
-- **Dark Mode**: Deep black (`#0a0a0a`) background with light gold (`#daa520`) accents.
-- **Transparencies**: Dark/Light toggling allows users to inspect PNG transparency against different backgrounds.
-
-## Implementation Details
-
-### Live Preview System
-
-Live preview is implemented using a client-side Canvas-based approach to provide instant feedback (< 100ms) without server round-trips.
-
-**How it works:**
-1. User uploads an image.
-2. The browser loads the image into an HTML5 Canvas.
-3. On any parameter change (width, quality, etc.), a debounced (300ms) update applies transformations to the canvas.
-4. The canvas content is displayed side-by-side with the original for comparison.
-5. File sizes are estimated from the Canvas data URL to provide immediate feedback on optimization savings.
-
-### Docker Strategy & Fixes
-
-PNGer uses a multi-stage Docker build to minimize image size and maximize security.
-
-**Optimization Fixes applied:**
-- **Dependency Installation**: Uses `npm install` instead of `npm ci` to handle missing lockfiles gracefully while maintaining stability via caret ranges in `package.json`.
-- **Security**: Runs as a non-root `node` user in the final Alpine-based image.
-- **Multer Upgrade**: Upgraded to `v2.1.0` for improved security and performance.
-
-## Local Development Setup
-
-### Prerequisites
-- Node.js 20+
-- npm or pnpm
-- Docker (optional)
-
-### Setup Steps
-
-```bash
-# Clone repository
-git clone https://git.alwisp.com/jason/pnger.git
-cd pnger
-
-# Setup backend
-cd backend
-npm install
-npm run dev
-
-# Setup frontend (separate terminal)
-cd frontend
-npm install
-npm run dev
-```
-
-### Environment Variables
-
-**Backend (.env):**
-- `PORT`: 3000 (internal)
-- `MAX_FILE_SIZE`: 10485760 (10MB default)
-- `CORS_ORIGIN`: http://localhost:5173
-
-**Frontend (.env):**
-- `VITE_API_URL`: http://localhost:3000/api
-
-## Development Workflow & Standards
-
-### Workflow
-1. **Feature Branch**: Create from `main`.
-2. **Develop**: Use hot-reload (`npm run dev`).
-3. **Test**: Perform manual testing of image operations and presets.
-4. **Commit**: Use `type: description` format (e.g., `feat: add rotation`).
-5. **Merge**: Merge into `main` after review.
-
-### Code Standards
-- **TypeScript**: Use strict types where possible.
-- **Svelte**: Keep components modular and under 300 lines.
-- **Async/Await**: Use for all asynchronous operations.
-- **Semantic HTML**: Ensure accessibility and proper structure.
-
-## Troubleshooting
-
-- **Port in use**: `lsof -ti:3000 | xargs kill -9`
-- **Sharp issues**: `npm rebuild sharp`
-- **Docker Cache**: `docker builder prune` if builds fail unexpectedly.
-- **Preview Glitches**: Check browser console for Canvas API errors.
