/* ==========================================================================
   Aramgah Memorial Garden Foundation — Design Tokens & Base Styles
   Single source of truth for the site's look. See /style-guide.html.
   Type scale is deliberately large: most visitors are elderly, and the
   header offers A− / A+ controls that scale everything further.

   CONTENTS
   1. :root design tokens (colors, type scale, spacing)
   2. Reset & base element styles (body, headings, links, lists)
   3. Layout helpers (.wrap, .section, .grid)
   4. Signature garden-path divider
   5. Buttons (.btn-primary / -brass / -outline)
   6. Cards, tables, forms, notices
   7. Header (two rows: brand+utilities, then nav) & mobile menu
   8. Footer
   9. RTL / Persian-mode overrides (html[dir="rtl"])
   10. Utilities, focus states, reduced-motion
