# Frame Studio — desktop app for Windows, Linux and macOS (same renderer as Frame Home, in a window with an editor
# UI). Everything it needs is vendored: Vulkan is loaded at runtime through volk (MoltenVK on macOS); the window is
# Win32 on Windows and GLFW elsewhere (studio/platform.h has the rest of the system). Presets: CMakePresets.json.
