• Remix: SSR performance, progressive enhancement
• SQLite: Simple, no external database needed
• SSE: Lighter than WebSockets for one-way updates

Why cyberpunk theme?

• Matches Dangerous Things brand aesthetic
• High contrast works well on small screens
• Dark mode saves battery on mobile devices
• Monospace fonts create terminal feel

Why no CSS framework?

• Frameworks add 50-200KB overhead
• Custom CSS is faster to load
• More control over design
• Easier to maintain
