Horizonis is a specialized tool designed to help you map out fictional star clusters and solar systems. While primarily tailored for the RPG Coriolis: The Third Horizon, its procedural generation and interactive maps are adaptable for any space-faring universe or tabletop campaign.

• Interactive Star Maps: Navigate through vast star clusters with a high-performance rendering engine.
• Solar System Exploration: Drill down into individual systems to view planets, moons, and other celestial bodies.
• Procedural Generation: Create unique, detailed systems on the fly using Rust-powered generation logic.
• Detailed Inspector: Access and manage technical data for every celestial entity.
• Multi-Platform Support: Use it as a lightweight web application or a powerful desktop tool.

• Frontend: Svelte 5 & SvelteKit
• Rendering: Pixi.js 8
• Desktop: Tauri 2
• Core Logic: Rust (via WASM for web and native for desktop)
• Styling: Tailwind CSS & Lucide Icons
• Monorepo Management: Nx & pnpm
• Runtime Environment: mise

This project uses mise to manage its runtime environment (Node.js, Rust, etc.) and pnpm for package management.
