t is Extract<ShaderType, { kind: 'vec' }>
설명
The emulated-double vector is the separate 'vec64' kind; test for it with
isVec64. Binary-op type resolution uses it (isMat(a) && isVec(b), isVec(a) && isScalar(b)) to decide between a vector-scalar broadcast, a matrix-vector product and a
same-kind op, and the .x/.y/.r/.g swizzle guards use it to reject a non-vector
receiver.
