/* ==========================================================================
 *  Drawer — right-side slide-out panel (modal cousin)
 *
 *  Used for entity-detail and edit surfaces that don't warrant a full modal:
 *  user/role drawers (xorizo permissions), cart drawer (build catalogue),
 *  Xori FAB drawer (app-core), etc. Three width variants: md / lg (default) / xl.
 *
 *  Markup (emitted by drawer() PHP helper or hand-written):
 *
 *    <div class="drawer-overlay" id="x" aria-hidden="true">
 *      <aside class="drawer drawer-lg" role="dialog" aria-labelledby="xTitle">
 *        <header class="drawer-header">
 *          <div class="drawer-title">
 *            <div class="drawer-title-name" id="xTitle">…</div>
 *            <div class="drawer-title-sub">…</div>
 *          </div>
 *          <button class="drawer-close" data-close-drawer="x">…</button>
 *        </header>
 *        <div class="drawer-body">
 *          <section class="drawer-section">…</section>
 *          <section class="drawer-section drawer-danger">…</section>
 *        </div>
 *        <footer class="drawer-footer">…actions…</footer>
 *      </aside>
 *    </div>
 *
 *  Open/close via `window.drawers.open(id)` / `.close(id)` (core.js).
