context.rs

1//! `Context` — the per-frame handle threaded into every render closure.
2//!
3//! This file defines the [`Context`] struct itself plus the dispatching
4//! facade that imports widget impl blocks from the `widgets_display`,
5//! `widgets_input`, `widgets_interactive`, and `widgets_viz` sub-modules.
6//! See [`crate`] root for the entry-point [`crate::run`] / [`crate::frame`]
7//! functions and `docs/ARCHITECTURE.md` for the 5-layer model that
8//! organizes which method lives where.
