/* =====================================================================
   CSI.CareerTrack.Client — app styles

   Theme tokens + LayoutFullApp chrome load from `_content/CSI.UI/csi-theme.css`.
   Rules here style only the app-local surfaces this shell owns.

   Every color uses a `var(--csi-*)` token that is actually DECLARED in
   CSI.UI (tokens.css / csi-base.css / themes/*.css). A token that does not
   exist silently renders its hex fallback and stops following the user's
   theme, so do not invent names — grep before adding one.
