Raster-image quad corners derive from a large f64 insertion point plus small u/v spans; the single-f32 cast quantized them at UTM scale. The ImageModel now keeps a corners_low residual, ImageVertex carries pos_low (location 2), and image.wgsl reconstructs the eye-relative position from the high/low pair.
