Detailed Description

3D vector template with arithmetic, geometry helpers, and RNG utilities.

This header defines a compact 3D vector type template, Vec3t<T>, that stores three components and exposes multiple alias views (x/y/z and r/g/b as well as an xy sub-vector). It provides arithmetic operators, length helpers, and common geometric operations (dot, cross, reflect, refract) useful in graphics and simulation code.

Note: The implementation uses a union with multiple member layouts (an std::array, two structs for aliases, and a 2D sub-vector). This is intentional for ergonomic access. Access only one active view at a time.
