Module ui_layer 

Screen-space UI layer — bypasses the 3D camera and renders in pixel coordinates.

The UI layer renders AFTER the 3D scene and post-processing but BEFORE the final composite. UI elements are pixel-perfect, unaffected by bloom or distortion, and positioned in screen coordinates: (0,0) = top-left.

Architecture

3D scene → PostFx (bloom, CA, grain) → UI Layer (ortho, no FX) → screen

The UI layer collects draw commands each frame via UiLayer::draw_* methods, then flushes them all in one pass via UiLayerRenderer.
