   EXHIBITOR LOGIN PORTAL — .exh-portal-* / .exh-*
   Shared by 13 pages: exhibitor-login.php, exhibitor-dashboard.php,
   and the 11 stall-detail forms. Split out of css/common.css on
   2026-09-06 (mobile perf audit). Frontend-only design pass — reuses
   existing tokens/.form-control, no new brand hex. Semantic status
   colors (green/amber) follow the precedent already set by
   #pop_enq_success/.notice-box elsewhere in this file/
   Education_awards.php.
