  Let $Y$ admit a rectangular Lefschetz decomposition of its derived category,
and consider a cyclic cover $X\to Y$ ramified over a divisor $Z$. In a setting
not considered by Kuznetsov and Perry, we define a subcategory $\mathcal{A}_Z$
of the equivariant derived category of $X$ which contains, rather than is
contained in, $\mathrm{D}^{\mathrm{b}}(Z)$. We then show that the equivariant
category of the Kuznetsov component of $X$ is decomposed into copies of
$\mathcal{A}_Z$.
  As an application, we relate $\mathcal{A}_Z$ with the cohomology of $Z$ under
some numerical assumptions. In particular, we obtain categorical Torelli
theorems for the lowest degree prime Fano threefolds of index 1 and 2.
