 ## Architecture
 
 ### Layered design
-- `src/main.cpp` — SDL3 window, event loop, shader-list scanning, dispatch to a backend.
-- `src/rendering/shader_backend.hpp` — abstract `IShaderBackend` interface + `ShaderMetadata` / `ShaderUniforms` / `ShaderProgramSpec` shared types. Two factories: `makeOpenGLBackend()`, `makeSdl3GpuBackend()`.
-- `src/rendering/opengl_shader_backend.{hpp,cpp}` — OpenGL 3.3 implementation. Loads `<folder>/<name>.gl.glsl` at runtime.
-- `src/rendering/sdl3gpu/sdl3gpu_shader_backend.{hpp,cpp}` — SDL3 GPU implementation. Loads `<folder>/<name>.frag.spv` (Linux/Windows) or `<folder>/<name>.frag.msl` (macOS); shares one passthrough vertex shader from `shaders/_common/passthrough.vert.{spv,msl}`.
-- `src/rendering/sdl3gpu/shader_factory.hpp` — small helper that loads a shader binary/source from disk and creates an `SDL_GPUShader`.
