/* ============================================================
   360eDash — Battery Station page styles
   Direvisi supaya konsisten secara pola layout dengan halaman
   System Information (kartu overview -> klik -> detail, stats
   row, badge, tooltip sumber data, timeline interaktif), sambil
   tetap berdiri sendiri (tidak bergantung pada css lain) supaya
   HTML/CSS/JS halaman ini bisa dipelihara terpisah. Semua class
   pakai prefix "bs-" dan token warna diambil dari css/global.css
   (--primary, --ink, --border, dst.) yang menjadi design token
   bersama seluruh dashboard (lihat guide.html).
