- VulkanShadowMap.cs: 2048x2048 D32_SFLOAT image, sampler (clamp-to-border), separate shadow pipeline (depth-only, no color, depth bias enabled, CULL_NONE) - Shadow shaders: shadow.vert (lightViewProj * model * pos), shadow.frag (empty) - Main shaders updated: fragLightSpacePos output from vertex, PCF 3x3 in fragment - Push constants expanded to 160B: model(64) + lightPos(16) + lightColor(16) + lightViewProj(64) - 3 push constant ranges: Vertex(model), Fragment(light), Vertex|Fragment(lightViewProj) - Descriptor set: 2 bindings — UBO(vp) + CombinedImageSampler(shadowMap) - Shadow pass: before main pass, renders scene depth from light position - Image transitions: shadow map UNDEFINED→DEPTH→SHADER_READ_ONLY each frame - vkCmdSetDepthBias(1.25, 0, 1.75) for acne prevention - Light VP: CreateLookAt(lightPos, origin, up) * Perspective(60°, 1.0, 0.1, 60) - 0 validation errors on build
