//! Subtitle/caption-domain sub-enum definitions used by `Commands`.
//!
//! Currently houses [`CaptionsCommand`]. The `Subtitle` and `Timecode`
//! variants on the top-level `Commands` enum delegate to sub-enums that
//! live alongside their handler modules (`subtitle_cmd::SubtitleCommand`,
//! `timecode_cmd::TimecodeCommand`) so they are not re-defined here.
