Detailed Description

2D vector template with arithmetic, length utilities, and helpers.

This header defines a simple 2D vector type template, Vec2t<T>, that stores two components and exposes multiple alias views (x/y and r/g). It provides basic arithmetic operators, scalar operations, length helpers, and a few convenience utilities (random generation, normalization, clamping) suitable for lightweight math and graphics code.

Note: The implementation uses a union with multiple member layouts (an std::array and two structs for aliases). This is intentionally done for ergonomic access (e.g., v.x vs. v.e[0]).
