1//! YUVA 4:4:4 planar 12‑bit (`AV_PIX_FMT_YUVA444P12LE`).
2//!
3//! Full‑resolution chroma + an alpha plane, 1:1 with Y. Mirrors
4//! [`super::Yuv444p12`] but additionally carries a per‑row alpha slice
5//! (also `width` `u16` samples, low‑bit‑packed at 12 bits).
6//!
7//! Ship 8b‑4 wires this format end to end. The per‑row dispatcher
8//! hands the alpha source straight through to the
9//! `yuv_444p_n_to_rgba*_with_alpha_src_row::<12>` SIMD/scalar path —
10//! per‑arch SIMD comes free because the BITS-generic 4:4:4 template
11//! already covers `BITS ∈ {9, 10, 12, 14}`, so the dispatcher selects
12//! SIMD when `use_simd` is true and falls back to scalar otherwise.
