- Nou: shaders/sprite.vert|frag, postfx.vert|frag, ball.vert (GLSL) - Nou: cmake/spv_to_header.cmake — converteix .spv → uint8_t C header - CMakeLists.txt: bloc non-Apple troba glslc, compila GLSL → SPIRV en build-time i genera headers embeguts a build/generated_shaders/ - gpu_context.cpp: MSL|METALLIB en Apple, SPIRV en la resta - gpu_pipeline.cpp: createShaderSPIRV() + branques #ifdef __APPLE__ per sprite/ball/postfx pipelines - Corregeix crash a engine.cpp:821 (Windows/Linux) causat per pipelines null quan init() fallava en no trobar suport MSL Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
