/* ============================================================================
   Printable worksheets (worksheet.js): the #screen-worksheet controls, the
   on-screen paper preview, and the @media print rules that print only the
   sheet on A4 (Chrome and Safari). Themes follow the year's pack:
   junior = big type and pictures, teen = calm and light (the sky palette), system font.
