/* ── Dark mode — OS-driven by default, with a manual override ───────
   Same custom-property convention used across the KG Apps suite:
   every color lives on :root, and this block redefines the same names
   with a dark palette. The login screen is intentionally pinned back
   to the light palette (see body.login-body below), matching the
   Hub's own sign-in page, which never goes dark.

   A manual toggle (see common.js) sets data-theme="dark"/"light" on
   <html> to override the OS setting; :not([data-theme="light"]) lets
   an explicit light choice suppress the dark media query, and the
   :root[data-theme="dark"] block below applies dark regardless of OS
   when the user explicitly chose it. */
