Struct BuildAnimationCtx 

pub struct BuildAnimationCtx {
    pub time: f64,
    pub scenario_time: f64,
    pub scene_duration: f64,
    pub fps: u32,
}

Frame-level context passed into the builder so animations can be resolved per-node and merged into the resulting CssStyle. When None, the box tree is built without any animation overrides (resting state).

Fields

time: f64

scenario_time: f64

Seconds since the scenario started, as opposed to time, which restarts at every scene. Only the audio-reactive binding reads it: the audio analysis is indexed on the scenario’s timeline, so using time gave a scene starting at t=73 s the analysis at 73 s into that scene. Every animation stays on time, which is what a delay, a stagger or a preset is written against.

scene_duration: f64

fps: u32

Frames per second of the output video. Required to convert the shutter fraction (in MotionBlurConfig) into an absolute temporal offset: shutter_window = shutter / fps seconds.
