// ============================================================
//  ATCuno - Console Companion App
//
//  ARCHITECTURE:
//  This app holds ALL state. The Arduino is a dumb display.
//
//  SCREEN ZONES:
//  ┌─ Aircraft list ──────────────────────────────────┐  ← Zone: Aircraft
//  ├─ API monitor ────────────────────────────────────┤
//  ├─ Panel [Routes|Live|DB] ─────────────────────────┤  ← Zone: Panel
//  └─ LCD preview ────────────────────────────────────┘
//
//  KEYBOARD (Aircraft zone active):
//    W/S = plane up/down  A/D = page left/right  Tab = open panel  Q = quit
//  KEYBOARD (Panel zone active):
//    W/S = row up/down    A/D = switch tabs      Enter = action
//    Tab / Esc = exit panel
//
//  FILES:
//    Models.cs      — Plane, PanelTab/State/Data, DisplayMode
//    Config.cs      — Config + appsettings loading
//    AnimState.cs   — LCD scroll/heading animation state
//    Formatter.cs   — LCD string formatting + Geo helpers
//    SerialHelper.cs— Serial port helpers + Display (Arduino push)
//    ConsoleUi.cs   — Spectre.Console rendering
//    TestData.cs    — Hard-coded test planes
//    AppState.cs    — Main application loop + input handling
//    Program.cs     — Entry point (this file)
