Use:

- Diagnostic UI shell.
- Win32 backend.
- DirectX 11 renderer backend.

Notes:

- Dear ImGui source is compiled into the application.
- This does not add any audio backend or audio-device access.
- Dear ImGui sample font binaries under `misc/fonts` are not bundled in this
  repository or the default source-review package. The GUI uses
  Windows-installed Japanese fonts at runtime.
- Unused Dear ImGui example prebuilt libraries are not bundled. The default
  source-review package includes only the ImGui core/backend source files used
  by this app plus `LICENSE.txt`: core ImGui files, `imgui_impl_win32.*`, and
  `imgui_impl_dx11.*`. It excludes unused backend sources such as Vulkan,
  WGPU, SDL, OpenGL, GLFW, Allegro, Android, Metal, and OSX, as well as shader
  helper directories, examples, docs, GitHub metadata, debug helpers, font
  samples, and prebuilt `.lib/.dll/.exe` artifacts.
