/* ===============================
   PLZ Map UI — Sidebar OVERLAY (All viewports)
   - Sidebar always slides over the map (no map push)
   - Add a dim overlay behind the panel for focus:
       <div class="map-dim" id="mapDim"></div>
   - Toggle JS (example):
       toggleBtn.onclick = () => {
         document.body.classList.toggle('panel-open');
         document.querySelector('.panel')?.classList.toggle('open');
       };
       document.getElementById('mapDim')?.onclick = () => {
         document.body.classList.remove('panel-open');
         document.querySelector('.panel')?.classList.remove('open');
       };
