/* reskin-materials.css — course-detail Materials panel interactions.
   The Import surface (#surface-import) was reskinned to the App_Shell handoff in
   PR2f and now lives in appshell.css under #lysia-root #surface-import; the
   former #surface-import rules here were superseded and removed. What remains is
   the #surface-courses materials drag / inline-edit chrome, still live (see
   courses.js: mat-kind-btn, mat-name-edit, is-drop-target). */

   Scoped under #surface-courses so it can't leak to the Import surface. The
   base chip/row/folder styling lives in style.css; this only adds the drag,
   inline-edit, and hover affordances for the per-course materials tree. */
