/* ============================================================
   The Johnston Family Story — stylesheet
   Design goals (Jerry is in his mid-70s):
   - Easy on the eyes: low-saturation warm palette, soft contrast
     (dark warm-gray text on warm paper, not black-on-white)
   - Highly legible: clean sans body, gentle serif headings
   - Adjustable text size (see the A- / A+ control in the header)
   - Big tap targets, generous spacing, durable system fonts only
