/* Kairos Vine — company site styles.
   Theme: warm parchment ground, deep evergreen vine, and a dawn-gold "kairos"
   light. Modern system sans for the UI, a serif voice for the Scripture moment.
   Single stylesheet, no build step. System font stacks only (no web-font fetch
   → no font-block CLS/LCP). Every visual is a CSS gradient or inline SVG (zero
   raster images), so the page stays small and fast. Mirrors the structure and
   a11y posture of the Bible Quiz landing, with a distinct parent-company look. */
