1//! P210 — semi‑planar 4:2:2, 10‑bit, high‑bit‑packed
2//! (`AV_PIX_FMT_P210LE`).
3//!
4//! 4:2:2 twin of [`super::P010`]: same Y + interleaved-UV plane shape
5//! and same high-bit-packed `u16` convention (10 active bits in the
6//! high 10 positions, low 6 zero), but chroma is **full-height** —
7//! one chroma row per Y row instead of one per two. NVDEC / CUDA HDR
8//! 4:2:2 download target and some QSV configurations.
9//!
10//! Per-row kernel reuses the 4:2:0 `p_n_to_rgb_*<10>` family verbatim
11//! (the per-row UV layout is identical to P010 — half-width
12//! interleaved); only the walker reads chroma row `r` instead of
13//! `r / 2`.
