C++20 consteval guarantees that a function executes strictly at compile time, turning mathematical algorithms (sine lookup tables, matrix inverses, hash tables) into static constants.

If a consteval function cannot be evaluated at compile time, the compiler raises a hard error rather than silently falling back to runtime.

We generate our entire trigonometric sine/cosine lookup tables at compile time into the binary read-only section (.rdata).
