Detailed Description

vector manipulation API

Provides simple, inline operations (set, add, sub, scale, dot, length, normalize, min/max, copy, cross, reflect) on fixed-size vectors.

Vector utilities for 2D, 3D, and 4D using bj_real.

All functions are header-only and suitable for high-performance code.
