//! Embedded animation fixtures (test-only): a 3-frame clip of a red
//! bar stepping across a gradient, written by real encoders, plus one
//! video file whose only job is to be REFUSED.
//!
//! Regeneration (Pillow writes the GIF and the APNG; the `.mp4` is
//! muxed here so the refusal path has a structurally real subject):
//!
//! ```text
//! pip install pillow
//! python3 tools/make_anim_fixtures.py OUTDIR
//! ```
//!
//! The script is byte-reproducible: re-running it rewrites exactly the
//! arrays below.
//!
//! Ground truth: frame `i` paints the two columns `1 + 3i` and `2 + 3i`
//! red (240,30,30); every other pixel is `(20 + x*8, 20 + y*8, 120)`.
//! The bar is two pixels wide and never touches the canvas edge, so a
//! lossy container's smear cannot move where it reads.
//! [`bar_column`] and [`expected_rgb`] mirror that formula.
