   assets/css/theme.css — the ISPBILLING look for every page
   Loaded after style.css. Same class names and CSS variables the pages already use
   (--primary, --surface, --text-main, .card, .btn, .table, .badge, .form-control ...),
   restyled: zinc greys, sky-blue brand, flat white cards, Inter / Hind Siliguri.
   Light by default (or the phone/PC setting); dark via html[data-theme="dark"].
   The brand colour is only the --brand-* scale below (+ the rgba() of brand-400/500/600 in a few rings):
   change those to re-colour the whole app.
