// The overlay composite: one premultiplied-alpha RGBA texture (the console UI's
// offscreen image) sampled over the swapchain. Blending happens in fixed function
// (src ONE, dst ONE_MINUS_SRC_ALPHA — Skia surfaces are premultiplied).
//
// Regenerate: shaders/build.sh (committed .spv, no build-time toolchain).
