// Layer-shader GLSL for the native composite compositor. Every program here is
// single-sourced from catalog/shaders/_shared/<name>.frag via build:shaders and
// read through ShadersGenerated; CompositeFactory links each with PASSTHROUGH_VERT.
// The generative backgrounds are likewise the generated GENERATIVE map.
//
// All are GLSL ES 3.00, matching the native GL context. image/subject/masked are
// the fixed compositor primitives (cover-fit image, masked camera person, masked
// scratch); each shaders/_shared/composite-*.frag documents its premultiply and
// mask-UV contract.
