/* ─── Theme Transition Animations ───
   Login page only — the global sidebar theme-toggle keeps its snappy
   display: none/inline-flex swap. Card surface, form inputs and labels
   use theme tokens (--surface, --text-*, --border-light, --danger-*).
   The :root @property interpolation in theme-transitions.css already
   eases every registered color token at 400ms — adding a local color
   transition here would re-trigger on every intermediate frame, causing
   the card to lag behind the gradient crossfade. So we omit color,
   background-color, and border-color from the local transition; the
   :root interpolation drives theme changes, and only box-shadow remains
   local so the focus ring keeps its snappy 150ms feedback. */
