//! Cotis context trait implementations for [`crate::renderer::RaylibRender`].
//!
//! Bridges Cotis's window/frame/render context traits and text measurement to raylib:
//!
//! - `CotisWindowContext` (`cotis_utils::traits`) — screen dimensions from raylib.
//! - `CotisFrameContext` — frame delta time.
//! - `CotisRenderContext` — provided automatically via blanket impl when window and frame contexts are implemented.
//! - `RendererTextMeasuringProvider` — layout text sizing via [`crate::functions_raylib::raylib_measure_text_inner`].
