   DESCRIPTION PANEL
   =========================================================================

   The panel uses a two-layer trick for a smooth open/close animation:
   - The outer .bk-jac__desc has max-height transitioned (0 → content height,
     set inline by JS from scrollHeight measurement).
   - The inner .bk-jac__desc-inner holds the actual padding, so closing the
     outer max-height doesn't affect padding interpolation.

    transition: max-height var(--bk-jac-duration) ease;

   and disables its tabbable children. JS removes it on open. */
