/* SIP Platform admin — design layer on top of Pico.css v2.
   Goals: cohesive spacing, dark-mode-safe status colors, a real top bar with
   tabs, compact tables, consistent buttons/badges, tidy forms. Keeps the
   historical class names (card, pill, pill-ok, muted, row, grid-2, form.inline)
   so existing templates keep working. */
