//! Captures the current git branch (and re-runs when it changes) and
//! exposes it to the crate as the compile-time env var `CUQUE_GIT_BRANCH`.
//!
//! Used by the HUD title to mark dev builds with their branch name so
//! side-by-side instances built from different branches are visually
//! distinguishable. When the crate is built outside a git tree — e.g.
//! from a crates.io tarball, `cargo install`, or a vendored source drop —
//! no env var is set and `option_env!` at the call site yields `None`.
//! Shipped release binaries are built from a patched-version tree inside
//! CI's checkout, so they DO see a branch here, but their HUD already
//! shows the real version so the branch suffix is suppressed downstream.
