Rules

Dear ImGui · balanced balanced

- Begin all frames strictly with `ImGui::NewFrame()` and strictly conclude with `ImGui::Render()`.

- Construct the UI layout strictly inside the rendering loop explicitly every frame in pure immediate mode methodology.

- Use `ImGui::PushID()` and `ImGui::PopID()` carefully to safely distinguish between structurally identical UI elements in loops.

- Keep business state strictly separated from UI logic — Dear ImGui should strictly read state dynamically and write back state seamlessly.
