//! Cluster A — open string enums w/ `Other(SmolStr)` and total `FromStr`.
//!
//! One `pub(crate) fn name(g: &mut Gen) -> T` per type, referenced from each
//! type's container-level `#[quickcheck(arbitrary = "crate::quickcheck_helpers::strings::name")]`.
//!
//! Pattern: 50/50 picks a curated slug or an arbitrary string — **both
//! routed through `FromStr`**, so every generated value is canonical.
//!
//! Owned types:
//!   - codec::{VideoCodec, AudioCodec, SubtitleCodec}
//!   - container::Format
//!   - subtitle::Format
//!   - audio::ChannelLayout, audio::SampleFormat, audio::ContainerFormat

// Both spellings of the 5.x pair are seeded on purpose. FFmpeg gives the
// unqualified `"5.0"` / `"5.1"` to the **back**-speaker layouts and
// qualifies the side ones, so seeding only the short pair reaches
// `N5Point0Back` / `N5Point1Back` and leaves `N5Point0` / `N5Point1`
// unreachable — exactly the half whose slug moved in 0.4.0.
