/* ---------------- UI-CLIENT-01 refinement ------------------------
   Hide the entire old pre-auth client header on guest pages only.
   The new .kwsm-cauth design already carries its own brand panel
   (logo + KWSM wordmark + title + features), so the legacy
   .client-header-shell strip ("بوابة العملاء" + subtitle + action
   buttons) above it is purely redundant for visitors.

   Scoping: client_layout.php sets `body.client-portal-guest`
   exactly when no client session is active (the audience of
   login / register / onboard). The logged-in branch keeps
   `body.client-portal-auth` and its full header (with
   `إضافة جهاز` + `تسجيل خروج`) untouched. Admin pages use a
   different layout entirely and are unaffected. */
