🧠 Architecture

• Core Layer
  Handles region parsing, pinging, firewall rule planning, and geo detection.

• UI Layer
  WinForms-based interface with custom controls, animated feedback, and dynamic presets.

• Data Models
  Immutable records for relays, regions, and raw SDR config.

• Interop
  Uses NetFwTypeLib for COM-based firewall rule management.

🛡️ Privacy & Safety

This app uses public IP-based geolocation and Steam's SDR config API.
No personal data is stored or transmitted.
Firewall rules are scoped to CS2 relay IPs only.

🔧 TODO

• Custom User Presets
  Allow users to define and save their own region combinations.

  • UI: Add a “Custom” radio group with editable region checkboxes
  • UX: Persist selections across sessions using local config or registry
  • Feedback: Highlight custom presets with a subtle accent color or emoji

• Ping Analysis & Recommendations
  Measure live ping to all regions and suggest optimal choices dynamically.

  • Logic: Implement async ping sweep with timeout handling
  • UI: Display recommended region with animated pulse or fade-in
  • UX: Show “Best Match” label with confidence score or emoji indicator
  • Performance: Ensure zero UI freezing during pinging
