16//! ECgFp5 elliptic curve and its scalar field, as used by the Lighter signer.
17//!
18//! - [`Point`] is a curve point on `ECgFp5`, with addition, doubling, scalar
19//! multiplication, and the canonical `Fp5` encode/decode pair.
20//! - [`Scalar`] is the prime-order scalar field modulo the group order `n`,
21//! with Montgomery-form multiplication and a signed-window recoding helper
22//! used by the variable-time scalar multiplication.
23//!
24//! Both modules sit on top of the field layer and contain no `unsafe`. Vector
25//! tests under `test_data/` cross-check against the upstream Go reference.
