/* ============================================================================
 * Kairos Vine — brand color tokens
 *
 * Hand-authored (this site has no token generator yet — unlike the Bible Quiz
 * landing, whose tokens.css is generated from brand/biblequiz.tokens.json).
 * Defines the --kv-* custom properties consumed by main.css. Linked first in
 * every page's <head>.
 *
 * Identity: a distinct parent-company palette, separate from the Bible Quiz
 * product. The name carries the system —
 *   • Vine   → deep evergreen + living green: abiding, growth, lasting fruit.
 *   • Kairos → warm dawn gold: the appointed light, the right moment.
 *   • Ground → warm parchment: the page of Scripture, not a cold UI.
 * All text pairs below meet WCAG AA (gold is decorative / large only).
