/* Tendance.ai — marketing landing page.
 *
 * Standalone by design: this shares the app's brand tokens by VALUE, not by
 * import. The app ships its own token sheet through a build step; duplicating
 * the handful of values here keeps the landing page a single static drop with
 * no bundler, and means a marketing tweak can never reach production styles.
 * If the brand moves, the source of truth is shared/design-tokens/design-tokens.css.
