//! Real (non-stub) headless GPU rendering for OxiUI, built on [`wgpu`].
//!
//! This module implements [`oxiui_core::paint::RenderBackend`] on a GPU target
//! that is created *headlessly* — there is no window or swap-chain surface.
//! Draw commands are rasterised into an offscreen colour texture which can be
//! read back to CPU memory for testing or off-screen export.
//!
//! Sub-modules:
//!
//! - [`device`]        — headless `Instance`/adapter/device/queue + offscreen texture.
//! - [`pipeline`]      — `solid.wgsl`, `gradient.wgsl`, `textured.wgsl`, `blur.wgsl`,
//!   and `composite.wgsl` compiled pipelines.
//! - [`buffer`]        — `#[repr(C)]` `Pod` vertex / uniform layouts + quad emitters.
//! - [`tessellator`]   — CPU path flattening and stroke/fill tessellation.
//! - [`texture`]       — image upload utilities and `TexturedDraw`.
//! - [`shadow`]        — ping-pong Gaussian blur + composite for `BoxShadow`.
//! - [`geometry`]      — CPU geometry builder, visibility culling helpers, and
//!   draw-segment / gradient-draw data structures.
//! - [`exec`]          — GPU pass execution helpers and [`FrameStats`].
//! - [`renderer`]      — [`WgpuBackend`] and the `RenderBackend` implementation.
//! - [`instance`]      — instanced rectangle rendering pipeline and renderer.
//! - [`render_target`] — off-screen render targets for cached subtrees.
//! - [`layer_cache`]   — GPU-backed render-layer cache with dirty tracking.
//! - [`ring_buffer`]   — streaming vertex/index ring buffer.
