/* ============================================================
   DigitalKiddo™ Maths — Learning Report Card
   ------------------------------------------------------------
   Premium school-style progress report for parents.
   Uses only the design tokens from style.css (--surface,
   --gray-*, --primary, …) so dark-mode.css themes it for free.
   Includes the @media print rules that power "Export Report"
   (browser Print → Save as PDF).
