oxframe-core 0.3.0

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