#![allow(unused_assignments)]

//! # aphrodite build.rs
//!
//! Embeds version, git commit hash, build timestamp, target triple, rustc
//! version, and build profile as compile-time environment variables
//! (`APHRODITE_*`) for runtime display in startup logs, health checks, and
//! version endpoints.
//!
//! CI (`Build.yml`) stages release artifacts per full target triple, e.g.
//!   aphrodite-x86_64-unknown-linux-gnu
//!   aphrodite-aarch64-apple-darwin
//!   aphrodite-x86_64-apple-darwin
//!   aphrodite-x86_64-pc-windows-msvc.exe
