This file is part of the Tannic Tensor Library and defines the Shape class, a compact, constexpr-friendly abstraction for representing the shape (i.e., dimensions) of tensors and expression-like objects. Shapes are integral to indexing, broadcasting, and tensor manipulation throughout the library.

The shape supports:

• Compile-time construction (constexpr)
• Convenient initialization from iterators, lists, or variadic arguments
• Safe indexing, including Python-style negative indexing

All expression-like objects in the library expose a Shape as part of their interface, making this file central to the Tannic design.
