Struct FadeThrough 

pub struct FadeThrough;

Material 3 “fade through”: the outgoing child fades 1→0 over the first 6/20 of the timeline then holds, while the incoming child holds at [FADE_THROUGH_SCALE_START] scale / 0 opacity for that 6/20 then fades in and scales up to 1.0 over the remaining 14/20. Non-directional (no slide) — reverse has no effect. The idiomatic pattern for a destination change with no spatial relationship (bottom-nav switch, account switch), and the reduce_motion collapse target.
