Variants

Scalar = 0

Single scalar value.

FixedArray = 1

Fixed-size array; length is implicit in the type ID.

RaggedArray = 2

Ragged / variable-length array (Vec-like).

Tree = 3

Tree node (recursive structure).

Graph = 4

Graph node (cyclic references).

HashBucket = 5

Hash table bucket.

Sparse = 6

Sparse / null-able slot.

UserDefined = 7

Reserved for caller-defined extensions.
