A circle $C_0$ is inscribed in an equilateral triangle $XYZ$ with a side length of 112. For each positive integer $n$, circle $C_n$ is inscribed in the region bounded by $XY$, $XZ$, and an arc of circle $C_{n-1}$. This forms an infinite sequence of circles that are tangent to sides $XY$ and $XZ$ and approach vertex $X$. If these circles collectively have an area of $m\pi$, find $m$.

Let's think step by step and output the final answer within \boxed{}.
