dioxuscut-core 0.1.2

//! `<Freeze>` component — pauses all children at a fixed frame.
//!
//! Equivalent to Remotion's `<Freeze>`.
//!
//! When rendered, provides a `TimelineContext` that is frozen at `frame`
//! regardless of the actual playback position.
//!
//! # Example
//! ```rust,ignore
//! use dioxuscut_core::Freeze;
//!
//! fn FrozenSection() -> Element {
//!     rsx! {
//!         // Always shows frame 10 — useful for poster frames
//!         Freeze { frame: 10,
//!             MyVideo {}
//!         }
//!     }
//! }
//! ```
