//! The engine-free half of the crate: plain `f32` maths with no `bevy` in it.
//!
//! `tests/leaf.rs` enforces that. The point is that the shapes of these curves — how a flame
//! flickers, how a light takes hold, how far a raised light reaches, how a flame's height and phase
//! are packed — are testable without an app, a window or a GPU, and are the part of the crate a
//! host is most likely to want to reuse in its own systems.
