/* ============================================================ *
 *  Pre-chat textarea size + centering fix.                     *
 *                                                              *
 *  Bug: the textarea was growing to ~170px tall because         *
 *  `align-items: flex-start` on the wrap pinned the cursor to   *
 *  the top of an oversized box. The wrap's natural height +     *
 *  the textarea's max-height: 110px combined with the wrap      *
 *  padding (10px × 2 = 20px) yielded a 130px+ block, and        *
 *  flex-start put the placeholder at the very top.              *
 *                                                              *
 *  Fix: lock the textarea to a comfortable 2-line height (44px) *
 *  + center it vertically in the wrap. Matches the active-chat  *
 *  input's visual density.                                      *
