   Pintaz Draf Studio - studio.css
   The drafting table skin. Loads AFTER base.css and reuses its tokens
   (--bg, --bg-card, --ink, --muted, --line, --brand, --shadow-card).
   Every class here is prefixed .st- so nothing collides with the landing
   pages. The one exception is the print block at the bottom, which styles
   the .draf-* sheet DOM that export-pdf.js builds.
