/* ============================================================
   AMS UI — a real component system, not an AdminLTE re-skin.

   Built on Bootstrap 5's grid/utilities/modal-JS only (a base
   framework, not "the template"). Every visible structural piece
   — shell, sidebar, topbar, stat tiles, panels, tables, pills —
   is custom here and does not use AdminLTE's small-box / info-box /
   nav-sidebar / app-wrapper classes.
