Let $\mathbf{w} = \begin{pmatrix} 3 \\ -2 \\ 1 \end{pmatrix}$ and consider the set of vectors $\mathbf{v}$ such that
\[
\operatorname{proj}_{\mathbf{w}} \mathbf{v} = \begin{pmatrix} 3 \\ -2 \\ 1 \end{pmatrix}.
\]
Find the equation of the plane containing all such vectors $\mathbf{v}$ and write it in the form
\[
Ax + By + Cz + D = 0,
\]
where $A, B, C, D$ are integers with $A > 0$ and $\gcd(|A|, |B|, |C|, |D|) = 1$.
