   Same fix applied to esm-theme.css (admin) -- mirrored here

   .app-shell is `display:grid` with .sidebar/.topbar/.main as
   grid siblings, and .content-scroll inside .main is a flexed,
   `overflow-y:auto` pane sized to fill the viewport. None of
   that is print-safe: a page's own @media print block hiding
   just .sidebar/.topbar isn't enough -- with the grid still
   active, hidden grid items still occupy their track, and
   .content-scroll stays clipped to viewport height so only
   the on-screen scroll position of the content prints (this
   is what made rcard.aspx's report-card table look "hidden"
   in print -- everything past one screen-height of the page
   was silently cut off, not just visually smaller). Fixed
   globally here instead of relying on every student page to

/* -- Mobile card-reflow for data tables ---------------
   Classic ASP.NET GridView rendering has no <thead>/<tbody> -- the header
   is just the table's first <tr>, made of <th> cells, with data rows after
   it. esm-student-shell.js's enableMobileTableCards() detects that first
   row, copies each <th>'s text into a data-label attribute on the matching
   column's <td> in every data row, and marks the table
   .mobile-cards-ready -- this CSS then does the actual reflow: hide the
   header row, turn every remaining row into a card, and prefix each cell
   with its column label (via the data-label the JS just set) instead of
   relying on a column position that no longer exists once cells stack.
   Runs on every table.table / table.rc-table found on any student page
   automatically -- no per-page markup changes needed, and no dependency on
   a .gt-panel wrapper (some pages, e.g. notices.aspx, build a plain
   hand-written <table class="table"> inside a .panel instead of a
   GridView inside .gt-panel -- this still needs the same treatment).
   !important is used deliberately here, not out of laziness: at least a
   dozen pages redeclare .gt-panel/.gt-panel table locally (their own
   inline <style>, since .gt-panel has no single global source of truth --
   see the earlier per-page duplication this session kept re-discovering).
   Those local rules can land before or after this shared stylesheet in the
   rendered <head> depending on each page's own markup, so equal-specificity
   cascade order isn't reliable here -- this must win regardless. */
