A std::span with N != std::dynamic_extent means:

It stores exactly N elements by value and rejects any span of a different extent

It is a fixed-capacity container that owns N elements and manages their lifetime

It can only view arrays with static storage duration and not heap or member buffers

Its extent (number of elements) is fixed at compile time and encoded in the type
