crates/monetize-admin/build/console_fresh.rs

//! **[console-stale]**: the console bundle (`monetize-ui-web/dist`) must be
//! newer than every source it was built from. Shared by `build.rs` (which
//! refuses the build) and `tests/console_stale.rs` (which proves it).
//!
//! MEASURED 2026-10-12: the ONE box shipped a `dist/` built 10-11 07:08, before
//! the usernameless-passkey fix; `build.rs` embedded whatever `dist/` held.
