/**
 * School ERP — Modern UI (v2.9.0)
 * ---------------------------------------------------------------------------
 * PRESENTATION ONLY. This file restyles the existing markup; it adds no behaviour and changes no
 * markup, field names, IDs, hooks or data. Every selector is scoped to the plugin's own screens:
 *   body.serp-ui   -> the plugin's wp-admin screens (class added only on ?page=serp-*)
 *   .serp-dash     -> the front-end Dashboard
 *   .serp-portal   -> student / parent / teacher / client portals
 *   .serp-portal-login -> login screens
 * Printed documents (report cards, ID cards, receipts, certificates, mark lists) are NOT touched.
 * Rules use a "body" prefix so they win over the original stylesheets but still sit below the
 * school's own Brand Design choices. Switch off any time: School ERP > Brand Design > "Classic look".
