//! Ferrous-specific scoring policy layered on top of upstream `klondike`.
//!
//! Upstream [`klondike::KlondikeStats::score`] owns the per-move point values
//! (move-to-foundation, flip-up bonus, recycle penalty, etc.). The functions
//! here are the Ferrous Solitaire house rules that upstream has no opinion on —
//! currently just the win-time bonus shown in the win modal.

/// Time bonus added to the score on a win: `700_000 / elapsed_seconds`.
/// Returns 0 when `elapsed_seconds` is 0 to avoid division by zero.
pub fn compute_time_bonus(elapsed_seconds: u64) -> i32 {
