 - strict numeric conversion by default, widening where valid, C scalar coercions at C boundaries, and explicit scalar keyword casts such as `i32(x)` / `c_float(x)`

 - pointer mutability via `mut`, optional pointers as nullable pointers, pointer arithmetic for many-item pointers, postfix dereference `^`, and trapping optional unwrap `?`

-- `std/mem` allocator contract over byte allocation: `Allocator` with `?*mut anyopaque` context plus `alloc`, `realloc`, and `free`; failed nonzero reallocation preserves the original allocation, while zero size frees it
