Type limits are spelled min-value and max-value, and quick formatting is to use a per-frame temporary allocator

 Decided 2026-09-25: the type-limit constants as a form taking a type, Odin's
 max(T), valid at any numeric type or a numeric?-bounded variable. For a float,
 min-of is the most negative finite value.
