1//! Human-readable names for the Rust target triples `mecha10 build` compiles for.
2//!
3//! Single source of truth for the `mecha10 init` "where will your robot run" prompt
4//! and the `mecha10 build <target>` platform-selection menu, so both stay in sync
5//! with each other and with the JSON schema's `buildTargetTriple` enum
6//! (`packages/core/src/schema_validation/schemas.rs`) instead of drifting.
