//! Shared domain value types — small `Copy`/`Clone` enums and structs that flow through
//! commands, contexts, and entities. Deliberately dependency-light so every other module
//! can lean on them without creating awkward import cycles.

/// How a `Command::Damage` arrived — an instant on-hit tick vs. a status ticking over time.
/// Exists so downstream tracking (DPS meters) can bucket the two separately instead of
/// blending "one big hit" and "many small ticks" into one number that's hard to read either
/// way. Also the reason DoT damage goes through `Command::Damage` at all instead of a status
/// mutating the enemy directly: routing it through the same queue as everything else means a
/// future global player modifier (e.g. "+30% all damage") only has to hook one place to see
/// every damage event, tagged, rather than needing special-cased access to the status system.
