+"""Batch fix for 课评汇总 class pages:
+1) Remove the 评星 (star rating) feature: strip each <div class="metrics">…</div> block,
+   delete star/metric CSS rules, and remove the dead star JS functions.
+2) Fix the 翻页卡死 (pagination freeze) on carousel pages: switch slides from
+   absolute-stacked opacity to display:none for inactive cards (only the active
+   card is ever laid out/painted), and remove backdrop-filter blur (compositing cost).
+
+Only applied to the first-week pages when <target> is the folder.
