//! `l0` — pure agnostic surface across every composite.
//!
//! The composites under `crate::ui::widgets::composite::*` are paint
//! pipelines + per-widget data types.  Each composite already
//! exposes a private internal draw function that takes only
//! `(RenderContext, rect, state, view, settings, kind)` — no
//! `LayoutManager`, no `InputCoordinator`, no `ContextManager`.
//!
//! The L1 / L2 / L3 wrappers (`register_layout_manager_*`,
//! `register_input_coordinator_*`, `register_context_manager_*`)
//! sit on top of those internals and add the framework plumbing.
//! Embedders that drive their own input pipeline (tessera, future
//! tui / web runtimes, custom L0 apps) only need the internals.
//!
//! This module re-exports them as one flat list.  No new logic — just
//! a stable, intention-revealing public surface.
//!
//! ## What's *not* here
//!
//! - `panel` — the current paint path calls `coord.widget_state(...)`
//!   inside the body to compute edge-handle hover; it's a real L1
//!   dependency.  Until panel is refactored to take hover state as a
//!   plain parameter it stays out of `l0`.  Use the L1 / L2 / L3
//!   wrappers in the meantime.
