1//! MSB-packed planar GBR 10-bit (`AV_PIX_FMT_GBRP10MSB{LE,BE}`) — three
2//! full-resolution `u16` planes in **G, B, R** order (FFmpeg convention).
3//!
4//! Samples are stored in the **high** 10 bits of each `u16` element (low 6
5//! bits zero), matching FFmpeg's `gbrp10msb{le,be}` descriptors (`shift = 6`).
6//! This is the exact inverse of the low-bit-packed [`super::Gbrp10`]
7//! (`gbrp10{le,be}`, samples in the low 10), so it carries a **dedicated**
8//! [`GbrpMsbFrame`](crate::frame::GbrpMsbFrame) whose
9//! [`try_new_checked`](crate::frame::GbrpMsbFrame::try_new_checked) rejects
10//! stray **low** bits.
11//!
12//! The marker carries `<const BE: bool = false>`: `Gbrp10Msb`
13//! (= `Gbrp10Msb<false>`) is the LE source; `Gbrp10Msb<true>` is the BE
14//! source. The walker [`gbrp10_msb_to::<BE>`] propagates `BE` from
15//! [`Gbrp10MsbFrame<'_, BE>`](crate::frame::Gbrp10MsbFrame) into the sinker
16//! dispatch.
