// Zero is a context-dependent count. An array dimension and a generic
// value-param count both ACCEPT zero — `[0]T` is a valid empty (zero-length)
// array, and `Box(0)` is a length-0 instantiation. (A `Vector` lane count
// rejects zero — see 1505.) This pins the zero-accepting half of the
// context-dependent count rule documented in specs.md (Array Types).
//
// Regression (F0.4 attempt 12): the spec previously claimed every count must be
// "positive integral", which wrongly implied `[0]T` / `Box(0)` are illegal.
