   DASHBOARD.CSS
   Page-specific styles for the student dashboard (topbar, profile
   banner, stats, activity tabs, quiz history, cart widget, streak,
   edit-profile modal, checkout modal, etc).

   REQUIRES styles.css to be loaded FIRST. This file omits anything
   that was an exact (or value-equivalent) duplicate of styles.css:
   the reset, html/body/a/img/button base rules, and the ENTIRE
   header/nav component — .nav-inner, .nav-logo*, .nav-search-*,
   .nav-links, .nav-link*, .nav-btn*, .nav-bell*, .notif-*,
   .nav-user-*, .nav-avatar*, .nav-dropdown-*, .mobile-bottom-nav,
   .mbn-*, and the slideDown dropdown-open animation trigger — all
   of that already exists in styles.css and needs no re-declaration.

   The one real header difference is called out below.

   MAIN NAVBAR — override only
   styles.css defines #edukated-header as position: fixed. This page
   needs position: sticky instead, so the header sits in normal flow
   directly under #edukated-topbar (which isn't fixed/sticky) and
   only sticks to the viewport top once you scroll past the topbar.
   Everything else (background, border, box-shadow, z-index) is
   identical to styles.css and is inherited, not redeclared.

   IMPORTANT: this sticky/fixed split is per-page, on purpose — pages
   with a topbar need sticky; pages without one should keep styles.css's
   fixed version. Mixing them (sticky header + styles.css's fixed-header
   .page-wrapper padding, or the reverse) is exactly the kind of thing
   that produces a stray gap around the header, so don't load this
   override on a page that doesn't also have #edukated-topbar.
