/// Compile-time hint for the OpenTelemetry span kind of a step span.

/// Contract: this enum is a *compile-time* hint supplied by the DSL compiler
/// when a `TracingProcessor` step span is built; the consumer converts it to
/// `opentelemetry::trace::SpanKind` once at construction. The enum is
/// `#[non_exhaustive]`: variants added in the future must degrade to
/// [`SpanKindHint::Internal`] at the consumption site, never cause a compile
/// failure downstream.
#[non_exhaustive]
