/* ZarchBot public site — "Orchard" theme.
 *
 * Visual reference is the Orchard neighborhood in Orem: fruit rows, blossom,
 * warm afternoon light, and the bench above them. Deliberately civic and warm
 * rather than devotional. It must not read as official Church branding, so the
 * Church's own palette, typefaces, and iconography are avoided on purpose
 * (see A2P_REGISTRATION.md).
 *
 * Accessibility targets: WCAG 2.2 AA. Every text pair below is >= 4.5:1, every
 * control border and focus ring >= 3:1, targets >= 44px, and the layout is
 * usable at 320px wide and at 200% zoom. Do not darken --leaf or lighten
 * --paper without re-checking contrast.
