// Commander X16 Emulator — ImGui debugger panel registry (C++).

//

// THE KEY TO PARALLELISM: every panel lives in its own .cpp under panels/ and

// self-registers via a file-static DebugPanelRegistration object. There is NO

// central list any panel must edit — debug_ui.cpp just iterates

// debug_ui_panels(). Five sessions can therefore each own one panel file with

// zero merge conflicts.

//

// To add a panel, create panels/<name>_panel.cpp:

//

//     #include "imgui.h"

//     #include "debug_ui_panels.h"

//     // (optional, to read emulator state) #include "debug_ui_bridge.h"

//

//     static void mypanel_render(bool *p_open) {

//         if (ImGui::Begin("My Panel", p_open)) {

//             ImGui::TextUnformatted("...");

//         }

//         ImGui::End();

//     }

//     static DebugPanelRegistration s_reg("My Panel", mypanel_render, true);

//

// and add the file to CMakeLists.txt X16_SOURCES. (The five foundation panels

// are already listed, so editing their *contents* needs no CMake change.)
