- Shaders
- CMake compiles GLSL via `glslangValidator` to SPIR‑V targeting Vulkan 1.2:
- Files under `shaders/*.vert|*.frag|*.comp` are rebuilt on `cmake --build`.
- Windows helper: `./compile_shaders.ps1` uses `glslc` with `--target-env=vulkan1.3` and supports additional stages (mesh/task/ray tracing).

- Validation Layers
- Enabled in Debug (`kUseValidationLayers = true` in `src/core/config.h`).
- Disable by building Release or toggling the flag during local experimentation.
