1//! YUVA 4:4:4 planar 14‑bit. FFmpeg does not ship a `yuva444p14`
2//! pixel format; this module exists for symmetry with
3//! [`super::Yuv444p14`] (which the colconv 4:4:4 BITS-generic kernel
4//! templates already cover) so callers can opt into 14‑bit YUVA
5//! through the same per‑arch SIMD path used for the FFmpeg-shipped
6//! 9 / 10 / 12 / 16 depths.
7//!
8//! Full‑resolution chroma + an alpha plane, 1:1 with Y. Mirrors
9//! [`super::Yuv444p14`] but additionally carries a per‑row alpha slice
10//! (also `width` `u16` samples, low‑bit‑packed at 14 bits).
11//!
12//! Ship 8b‑4 wires this format end to end. The per‑row dispatcher
13//! hands the alpha source straight through to the
14//! `yuv_444p_n_to_rgba*_with_alpha_src_row::<14>` SIMD/scalar path —
15//! per‑arch SIMD comes free because the BITS-generic 4:4:4 template
16//! already covers `BITS ∈ {9, 10, 12, 14}`, so the dispatcher selects
17//! SIMD when `use_simd` is true and falls back to scalar otherwise.
