//! The sources of Nova's standard library, `std/*/lib.nova`, embedded at
//! build time so the compiler stays one self-contained executable.
//!
//! Every `include_str!` path stays inside this package, so `cargo package`
//! carries all 17 files, and its verification step builds the packaged copy
//! on its own (spec
//! `docs/superpowers/specs/2026-10-07-phase-3-0-foundations-design.md` ยง3).
//! `nova-resolver` gives each module its `$std.*` name and its place.
