//! # Build script for GERMANIC
//!
//! Two responsibilities:
//! 1. Copy practice schema from source-of-truth into crate directory
//!    so that `include_str!` works for both `cargo build` and `cargo publish`.
//! 2. FlatBuffer bindings are pre-generated (no-op, see ADR-009).
//!
//! ## Regenerating FlatBuffers after schema changes
//!
//! If you modify `.fbs` files, run:
//! ```sh
//! ./scripts/regenerate-flatbuffers.sh
//! ```
//! This requires `flatc` (brew install flatbuffers) and will update
//! the pre-generated files in-place.
