1//! YUV 4:2:2 planar (`AV_PIX_FMT_YUV422P`, `yuvj422p`).
2//!
3//! Three planes: full-size Y + half-width, **full-height** U/V.
4//! The per-row kernel is identical to [`super::Yuv420p`]'s — the
5//! 4:2:0 → 4:2:2 difference is purely vertical: YUV420p reads chroma
6//! row `r / 2`, YUV422p reads chroma row `r`. The sinker calls
7//! [`crate::row::yuv_420_to_rgb_row`] directly.
