/* ===========================================
   Range picker (partials/_range_picker.html, js/range_picker.js)

   Quick tabs + "More ▾" (preset-tabs), and a panel with Customize (From–To fields,
   "Last N hours / days") beside the searchable quick ranges. The panel is
   fixed-positioned under the More button by the JS (so card overflow never clips it);
   on phones it is a bottom sheet over a scrim.
