## ✨ Key Features

- 🚀 **Extreme Performance:** Instant load times with zero-dependency architecture.
- 📦 **Single-File Deployment:** Optimized via Vite to a single, portable HTML file.
- 🔗 **Smart Link Sharing:** Entire drawings are compressed into ultra-short URLs using a custom binary codec—no database required.
- ✍️ **Natural Feel:** Smooth, pressure-simulated brush strokes and intelligent shape recognition (e.g., auto-snapping circles).
- 📱 **Fully Responsive:** Works seamlessly across Desktop, iPad, and Mobile.

---

## 🛠️ The Tech Stack

- **Custom Binary Codec:** Uses Varints and ZigZag encoding to serialize canvas data into compact Base64 strings for URL sharing.
- **RDP Path Simplification:** Implements the Ramer-Douglas-Peucker algorithm to keep stroke data lean without losing detail.
- **Vite + GitHub Actions:** A modern CI/CD pipeline that automatically builds and deploys the modular source code into a minified, single-file production build.
