Detailed Description
--------------------

Provides a fixed-size ``ct_string<N>`` that can be constructed at compile time, concatenated, compared, and converted to ``std::string_view``. Also includes:

- a consteval ``to_ct_string<N>()`` that renders an integer template arg to a ``ct_string``,

- a user-defined literal ``"_ct"`` that turns a string literal into a ``ct_string``,

- an overload set combiner ``match{...}`` for pattern-style visitation,

- a ``foreach_indexed<Ts...>(fn)`` that invokes ``fn.template operator()<T, I>()`` for each ``T``.



Requires C++20 for class NTTPs used by the ``"_ct"`` literal.
