   Ported from the cursivewritingsheets.com "bound handwriting manual"
   direction. Visual layer only: no markup, copy, keywords, structure or
   tool behaviour are touched here. Every selector maps to existing
   generated HTML.

   Direction: a bound writing manual. Source Serif 4 for headings and prose,
   Inter for tool chrome. Real material throughout — paper grain, ruled
   stock, a leather desk under the preview, engraved frames, gold hairlines,
   and a dark cloth-bound footer.
