/* ==========================================================================
   That's Write! — "Exercise book" theme
   --------------------------------------------------------------------------
   The one shared stylesheet for the whole site. Every page links this AFTER
   its own inline <style>, so anything defined here wins over the page's own
   copy of the same rule. The idea: paper, ruled lines, masking tape, red-pen
   marks — a real KS2 workbook, not a dashboard.

   Fonts: Caveat (brand), Patrick Hand (headings, labels, buttons, the
   pupil's own writing), Andika (body — designed for beginning readers).

   Conversion status — pages that have been moved over to this theme have
   had their duplicated inline CSS pruned; pages not yet converted still
   carry the old cream/white/orange styles and don't link this file yet.
