//! The raw balancing numbers (ADR-0001).
//!
//! **Every value in this file is a placeholder.** None of them has been tuned, and four of
//! the numbers this file will eventually hold are not derivable from any source at all
//! (see issue #8) — they can only be found by playing. Treat a value here as "a number that
//! lets the skeleton walk", never as a design decision.
//!
//! This is the only file in the crate that holds balancing numbers. Gameplay code never
//! sees these constants; it reads `Res<Balance>` (ADR-0001, decision point 4).
