Wraps wlroots' C ABI behind owning types (Display, Backend, Compositor, Output, XdgShell/Toplevel, Seat/Cursor/Keyboard, Scene/Node/Tree) with wl_signal -> std::function callbacks. Links the scenefx effect engine and ships a wlr::fx animation helper. Includes a runnable tinywl-style compositor and a scene/blur demo. License: AGPL-3.0-only.
