1//! Core of oxframe: signals, tweens, easing and a deterministic,
2//! single-threaded coroutine executor.
3//!
4//! > **Status:** oxframe is under very active development. The API is not stable yet and
5//! > may change from version to version. Pin the exact version in your Cargo.toml and check
6//! > the [changelog](https://github.com/oxygenframe/oxframe-sdk/blob/main/CHANGELOG.md)
7//! > before upgrading.
8//!
9//! An animation is an `async fn`; every `.await` on a [`Tween`],
10//! [`wait_for`] or [`next_frame`] is a frame boundary. One poll of the root
11//! future is exactly one frame, with a fixed `dt = 1 / fps`.
