/* =====================================================================
   Jagdish Memorial Public School — Staff Portal (C-Panel) Stylesheet
   Loaded together with style.css, which supplies color tokens, buttons,
   form fields, and card/alert styles. This file adds the dashboard
   shell: sidebar, topbar, data tables, and stat cards.

   Signature motif: the sidebar carries a thin gold "ledger margin"
   rule — a quiet nod to a school register/attendance book, echoed in
   the monospace figures used for every data stat.
