/* ZestyWorksheets — shared design system
   Playful "craft table" palette: warm paper background, coral primary accent,
   teal + yellow supporting accents. Distinct from ZestyTools (neutral utility)
   and PlainTally (conservative finance). No external fonts/requests — system
   font stack only, kept heavy on headings for a chunky, hand-labeled feel. */
