   AICAS Library — restyled onto the same design tokens and
   component language as the AICAS Examination module (single
   sticky topbar, gradient-brand accents, collapsible sidebar
   groups, soft card/table/badge system). Class names are kept
   from the original Library prototype; legacy variable names
   below are aliases so existing markup needs no changes.
